"Aside from your
headphone cables being beautifully made and offering upgraded
performance to my cans that is just so splendid, I had to drop you a
note commending your operation in terms of customer service and
expertise. I can't remember when I experienced such prompt replies
along with a wealth of detailed recommendations and careful advise."
"Hi, I just wanted to let you know I have had
great results with your Endorphin Power cable I bought about a year ago (and just ordered another one). I posted a
review on head-fi in the Amps forum here:
Thank you for this great product."
phrase of high end dealers seems to be that this or that piece
of esoteric equipment will make a difference "that is not
subtle." Usually true: sometimes I can hear no difference at
all, much of the time the improvement is slight, rarely is it
dramatic. Your Sennheiser cables belong in the third category.
The word that comes forward all the time when listening is
"pure." Pure sound without all the extraneous baggage that
usually accompanies the sound. I could hardly believe that a
"mere cable" could make that much difference. With all my work
on improving other elements in the sound chain, the weak link
introducing tons of garbage was the headphones cable. Again and
again, CDs that I could barely listen to before have now become
a joy. Violins sound like violins, period. Out of the box, the
ensemble, full fff sound had a slight harshness, slight but
present. Now, after less than a week of playing, that harshness
is 90% gone. In a word, these cables have improved my system —
no, improved the quality of the classical music I listen to —
far more than I believed possible. Thank you."
"Just writing to compliment how
extremely helpful you have been through this whole process and
to let you know that everything has worked out and gone beyond
my expectations. Your time, the great headphone system cables
you offer along with very accurate component recommendations all
added up to a wonderful sounding headphone system."
burning in the E-Series cable for my HD600 and with the mods you
suggested I absolutely love the performance!"
"Hello James. Just had to
drop you a quick email to say how good it 'sounds' to be
re-united with my Endorphin cable - well worth the wait,
which only served to highlight the short comings of the HD800
stock cable! Thank goodness for your cables which really allow
the headphones to fulfill their full potential. Thank you again
for your second to none after sales service which is a credit to
you and a pleasure for me to use."
the HE-6 - incredible!!! - so articulate, great bass, fast,
smooth and natural - blows away my Stax!!!"
arrived and everything was perfect.
And it's a funny thing - first listen and stereo was much
significant in other aspects. It expired a week
later and ... I don't know, maybe I began
to really listen or maybe - I don't know how to say it in
English - Your

"Just received the HiFiman HE-5LE
headphones and cold out of the box they clearly are in a league
above the Senn 650's. Especially like the bass-mid-treble
coherence and extension- nicely balanced to my liking. Also,
much more 'you are there' presence vs. the usual in-your-head hp
effect. No obvious sacrifice of bottom-end vs. Senns either. I
can already hear that the voicing is similar to the Senn 650, as
you suggested. Clamping force a bit tight to start but can tell
not like the 650's and trust they will loosen. finally, the
Anedio not having any problem driving the load. Thanks for the
recommendation - your response to my price/performance spec
appears to be spot on"
"Got the Endorphin for my Audez'e!
The sound performance is fantastic!"
Endorphin from my Mclntosh power amp to my HE-6 headphones I've
discovered the most wonderful sound which has put me front row
center stage at the best concert halls across America. Whether
the billing is Jazz or Classical the performance is top notch
and now the HE-6 connected to the Endorphin bring to my ears a
exquisite combination of true live sound in an acoustically
"Man! I just wanted to let you
know how dull and lifeless my P5's were before upgrading to your
E-Series cable. Great look and sound, Thanks."
ago I discovered how much cables can influence system sound. I
struggled for years trying to get the "perfect sound" with
expensive component upgrades all which came up short until I
purchased your Equinox cable for my HD650's. It was the perfect
solution and nothing else was necessary. My recent acquisition
of the LCD-2's and your Endorphin headphone cable has proven to
be even more influential on the LCD-2's performance and system
sound as a whole. Wonderful gains in clarity, depth and impact
with a great sense of realism which really immerses me intensely
into the music. What you accomplished with this cable has earned
my respect.........PS: I'd tried the ALO LCD-2 upgrade cable and
it falls flat in comparison."
"THANK YOU!! I just got the E-Series
for my HD650..... it feels/sounds SO GOOD. THANK YOU for making
"My P5 headphones
have come alive with your E-Series headphone cable and I could
not be happier with this purchase. This is the biggest
step up in sound quality I have ever experienced from a cable."
"I'm so impressed with your
Endorphin headphone cables for my HD800 and HE-5 LE headphones
that I just had to send you a quick note. They replaced the ALO
headphone cables I was previously listening with and now I
understand how inferior these cables are. The Endorphins are far
superior to the ALO's offering much greater dynamics and
transparency with a deep, wide soundstage and the added
sensation of richly textured tones of both voice and instrument
and that makes listening such a pleasure!"
for the Audez'e LCD-2's is like going from a Smart Car to a
Porsche and the application of your Endorphin power cable set to
the system was like getting a complete tune-up as the sound has
gone from rough and edgy to smooth and detailed. I love the ride
now. Great products....Thank You!
"Haven't let you know that I've been running in
the cable everyday since I picked it up last minute on the
last day of last year. I didn't want to make any comment
because I found that the cable experience very different
characteristics during the first 10 days or so. from bass
heavy to treble harsh bass light. It finally settled down and
I am now happy to say, it's a very good cable. as good as
advertised, transformed my hd800. Well done James! I will
write some impression on the major Chinese headphone club
forum once time frees up."
"A few weeks ago I
order the E-Series for my HD600's based on many positive Equinox
reviews and comments I found on the internet. I could not be
more pleased with the improvements. Prior to my purchase, I had
entertained upgrade cables from ALO, Cardas, Apuresound etc. all
which made there way to Audiogon in a fairly quick fashion. But
right from the start and even before break in, I heard a very
detectable signature of realism in the music. The HD600 now had
much greater depth, clarity and a distinctly full, organic
characteristic I never experienced with any other headphone
cable before. I also managed to pick-up a used Equinox and was
also very impressed. It does not have the clarity and ability to
go as deeply into the music as the E-Series, but it has many of
the for mentioned attributes and makes a very fine cable for
portable use. I'll contact you after the new year to engage in
your headphone system upgrade process. Thanks for offering a
cable that is so effective and truly leaves me with the feeling
it was money well spent."
"I just wanted to write back and thank you again for all that I
have learned from you in the past couple of months. The process you took
me through upgrading my system was so enlightening and
enjoyable. The combined changes you proposed had a huge impact
on the quality of sound. I truly was not aware listening to
music with headphones could reach such a high level revealing
and dynamics. Now I understand that headphone and power cables
were a large part of the problem. Prior to your process, I
used the Head-fi site as my source of information concentrating
on their featured headphone cable products. In turn, and as you
also mentioned, this was the stumbling block as all the cables
offered very little improvement along with introducing a variety
of new problems related to balance, clarity, soundstage and
musicality. Well, finally I'm at the place I want to be. My
system is well balanced with phenomenal sound from the HD800's
and the Endorphin cable. And as you indicated, is made even
better with all my components fueled by a pure power signal
delivered by the ribbon power cables. Thanks for your patience,
honest and effective recommendations."
"The application of you Endorphin cable set to my system has worked out to a much greater benefit
than anticipated! I expected improvement but what I experienced
was a new dimension of sound which I never expected from the
headphone medium. I even went as far as isolating each cable of
the set noting the impact of each improvement and although very
noticeable, the real excitement was is the combined improvement
brought about by the whole!"
" I'm glad my friend recommended
your headphone cable as he was spot on in his description of how
greatly my HD600's would improve. He also was thoughtful enough
to steer me away from all the other headphones cables featured
on Head-fi as he explained they are poor options in comparison
and promoted because of the revenue received by HF from the
cable makers via sponsorship fees. Makes sense, as I A/B-ed your
E-Series with several of the ones featured and was happy to
experience how much better my HD600's performed in comparison.
Thanks for a true high performance headphone cable!"
" Hello, hope
you are fine. The Endorphin HD800 WS headphone cable is great. I
now have fantastic sound quality and there is still more
burn-in to go."
"Man you guys
have come a long way from the days of the Equinox cable!!! Your
new Endorphin for the HD600's is something else by which I mean
it takes these phones to a level of incredible performance. The
background is now "pure black" and I'm hearing
all the great details of music without the hard to describe
characteristics that degrade the sound. I've tried Cardas, ALO,
Moon Audio and just about every other cable and not one has come
close to the Endorphin. In conclusion, mating the HD600 with the
a top shelf combination and money well spent as this combo
performs as well if not better than the best of the best."
built with performance enhancing qualities for my HD650
headphones I never thought would be realized, your E-Series
headphone cable upgrade has changed my listening experience to
one of great pleasure. thank you."
"Holding the Endorphin headphone
cable in my hand it exudes fine, detailed hand made workmanship.
Connecting it to my Audez'e LCD-2's it conveys performance like
I've never experienced from a cable change! As for your
Endorphin power cables, they have increased component
performance ten- fold! Thanks for the great products and
direction to truly effective and system correcting upgrades."
"Hi James, the Endorphin
ribbon power cable has been broken in for 5 days. It magically
balanced my system even at the first second I plug it in. I can
easily tell this drastic change without any necessity of AB
compare. It is hard to believe such a light and flexible cable can make that "big" a difference in the overall sound!"
"Absolute MAGIC!!!! That is my experience
upgrading my HD650 cable from the ALO to your Endorphin. In my
numerous A/B tests the ALO falls flat as the Endorphin reveals
superior detail, soundstage and most importantly deep punchy bass.
Headphone listening with this level of realism is extremely
enjoyable. Can't thank you enough for this fine product."
"OMG I do not know what I
was thinking using the Cardas all these years and not checking out
your E-Series HD600 cable. IT IS AMAZING!!!! This headphone cable
performs so well it's like I just bought a HD600 headphone
re-designed by Sennhesier that corrected every complaint I had
about these cans. Wonderful job and an example of truly effective
"Everything arrived today! The Endorphin HD800,
Power and Balanced Interconnect cables are astonishing, I have
never heard the 800's sound so good. Thanks so much."
"In the grand arena of audio
upgrades, I have reported back to let you know your Endorphin
headphone system cables - HD800, power and IC cables are
Your helpful advise has open me up to a very satisfying level of
"Thanks for all the good advice. After
replacing the cable, my 650 sounds like a new headphone. While
initially dubious about the value of the cable, I can't imagine
going back to the stock cable. Maybe someday I will be able to
afford your higher end cables."
"Hello James, Sorry for keeping
silence for so long. I was busy getting the full taste of using
the Endorphin cable after some burn-in period. In general the
effect of using the Endorphin with my Sennheiser HD600 appeared to
be much higher than I have expected. HD600 demonstrated incredible
improvement in every detail after rewiring. The highs has
become very detailed, crystal clear and full of air. And
no unpleasant or fatiguing feel even for long period of
listening! Mids have brought singers' voice in a natural and full
bodied way. The bass appeared to look a little light weighted
predominantly due to more detailed and deep character. Overall I
understood my Creek amp needs to be upgraded as it cannot fully
support the new level of HD600 performance ability. Another idea
is to try your interconnect for wiring my CD player with the
headphone amp. I will get in touch with you in a while on that.
Thank you for your great product and support."
"With an exceptional
product and excellent customer services, what more could this audio
nut ask for. Love your E-Series for my 600's!"
"Man you guy's aren't kidding, the stock cable was destroying the
sound of my HD800's. Even before full break-in these cans are
smoking with the E-Series attached. I've never heard better sound
from a headphone with this upgrade!"
search ended for a true high-end headphone experience just after I
connected your Endorphin headphone cable to my HD800's. Clean,
detailed with wonderful midrange and bass. What more can I say, I'm
in headphone heaven."
"The Endorphin is a true high-end headphone
cable. Everywhere you turn you see other manufactures using this
term and it couldn't be further from the truth. On the other hand,
I've never experienced such realism in the music until I connected
your Endorphin cables to my HD800's and 600's. I could go on and on
in great detail but let me just say my jaw is still touching the
"Hi James, I got the Endorphin
today. It only burn-in for 3 hours now, but the result is awesome! I
can not say enough, it is just the music! Thank you so much for your
and outstanding creation!"
"Hi James, Thanks for
the info again. The cable arrived today. It's amazing. My HD25s have
not left my head. I am seriously impressed. Keep up the amazing work."
"Bravo, not only does
your new Endorphin HD800 cable look great but it performance as
specified giving birth to how a top shelf headphone should sound!"
"James, based on how effective your Endorphin headphone cable is with
my HD650's, my suspicions are you are ahead of your time with your
designs. As I was, I think most users are expecting a really good
looking cable that performs like say a Cardas. After first listen and
long before break-in, it is realized the Endorphin means business
going far beyond the entire group of other headphone cables options
which are by comparison run of the mill sound quality wise . Moving to
your headphone system cables, the power and IC cables take it to an
even higher notch and I'm not sure I can go back to listening to
speakers." Have you any cable designs to cure my monitors?"
James S Serdechny, I
just wanted to thank you for the fantastic cables, that you are
creating!! A long time passed, but I was patient. Just now I
installed them to my Grado PS-1000 and Ultrasone E8. Installation was no
problem for me, following your comprehensive instructions. Everything
turned out to be quite easy. But the sound!!!! WoW!!! I know what
difference a cable can make to the sound (I use 99,99% pure platinum
wire as phono cables and I/C in my system) but I was taken aback!!! I
haven't expected SUCH a difference with your cables!!! Thank You, that
is a great product You are building!! Best regards"
you! You really know your business as the implementation of your
headphone system improvement plan has set a new standard for me which is
a level of excellence
I never deemed possible. Things REALLY changed with your headphone,
power and interconnects cables, like going from a Toyota to a Ferrari!
Now back to the autobahn."
"Just writing you back to
thank you. You were quick on the horn, firing back detailed answers to
my questions and your cables really do speak for themselves. As you
indicated, I am experiencing major changes in the sound with the
addition of the Endorphin for the HD800's, but the real shocker were the
power cables. I was
skeptical that they would have as much influence as you indicated but I
Very satisfied with your service and products."
been dabbling in expensive audio equipment for as long as I can remember
and I can testify that your Endorphin system cable set has put listening
to recorded music with headphones on the high-end map. Now listening
with the HD800's is strikingly close to my Sonus Faber's and I'm
catching details in the music never before heard."
" I truly did not believe
the change for the better after connecting your Endorphin power
cables for my components. I'm impressed and perplexed at the same time
but most importantly I'm grateful for your honesty and tremendous
patients with my many inquires.
I am truly convinced Stefan AudioArt is dedicated to offering the best
solutions which ultimately leads the customer to their desired goal.
"The stock cable of my Sennheiser HD800 was recently replace with your
Endorphin WS and the gains in the overall performance have been
substantial. Gone is the over emphasized treble (which was the biggest
problem I had experienced with the HD800) and what is left to enjoy is
pure playback magic as I did not have to make any other changes to my
system. The Endorphin has exceeded all my expectations of a single
system upgrade and has made it possible to become totally emerged in the
music with the pleasant feeling I'm in a live music setting. ......PS
the Endorphin feeding my 800's now surpasses my speaker performance
which I have invested four times the amount of money and that says a lot
about your wonderful design insight."
"After removing the Cardas
and connecting the E-Series to my HD650's, I haven't been able to get
enough sleep as I can't pull away from the music I've missed using the
Cardas all these years. What a difference as the E-Series adds magic to
the music heard through the 650's. The instrument presents sends shivers
through my body and I feel as
if I'm in the front row seat of a live concert. Your cable is worth
every penny - thanks."
from France! Purchased your Endorphin cable for my HD800 and enjoying
the spectacular sound never before experienced from other headphones in
my large high end collection. Could not be happier with the performance,
comfort and look this cable displays."
"To find a company such as
Stefan AudioArt making products that are made and perform so incredibly
well was a God send. The component upgrades and tube rolling I've done
in the past did not compare to the incredible results I achieved with
the Endorphin power/ IC cabling, E-Series HD650 headphone cable and
mapleplatforms. Your passionate advise and help through the entire
process is rare and unique dimension and I have greatly appreciate this
- thank you."
Endorphin balanced ribbon interconnect is a masterpiece! It is wide

and the most actuate upper-end I've ever heard from any IC even ones
I've used costly 5 times the price."
"I "toned-up" and read the
Tone Audio review of your Equinox (now apparently the E-Series) HD650
headphone cable before my purchase and delighted to report they were
right on the mark. The E-Series blows away the Cardas and much more than
the review indicated! Nice design. Now I'm seriously looking at your
power cables and interconnects to further improve what your headphone
23 years of enjoying top audio components your Endorphin high-end
headphone system cable set is at the forefront of my most memorable
upgrades. My Grado PS-1000 absolutely sing and all my complaints
regarding the musical presentation are that of the past as this cable
set has made what I thought impossible - possible."
“I need 3 more power cords and 1 IC. Your stuff absolutely rocks……… I
couldn't be happier with the sound from your stuff. Your IC's have
beaten Crystal Cable, Shindo and ASI Livelines in my set-up. I had the
Omega Mikro stuff before but it was way too lit-up on top. Not quite
sure why your IC’s don't suffer the same problem.”
"I am happy to report back that my
Grado RS-1 are now singing so sweetly with the Endorphin high-end
headphone cable. These beautiful headphones can do no wrong
with your Endorphin attached listening to the wide range of collected
recorded music I own. The excitement and pleasure of listening to all my
old records is back and I'll be back soon for a re-cable of my

quite awhile since I have experienced a product which has such a
positive influence in the performance of my system. The Stefan AudioArt

richness in sound I did not think existed. Happy to be a customer and
experience the benefits of such an effective product."
"As a long time fan of Grado RS-1
headphone I decided to incorporate your new Endorphin headphone cable
option as one of the several upgrades towards a new headphone system.
This upgrade has proved so important that I have redirected my plans
towards upgrading the cables in my system instead of changing
will contact you in the coming months for specific instructions on
upgrading my power and IC cables. Thanks for the sincere and well
crafted recommendations which are going to save me a lot of money and
most importantly will deliver a much high level of fidelity."
PS1000 are out of this world with the upgrade to your Endorphin high-end
headphone cable! The balance and transparency of sound is nothing short
of astonishing. The Endorphin has proved to be the most important
upgrade I have ever experienced in a headphone system environment.
Thanks for engineering a product that provides true sonic inspiration."
"Uninspired by my new Sennhesier
HD800 headphones I went to the web to search for a possible solution and
can across you site. Purchasing both a VOICE and Endorphin for my single
set of 800's, I was so stunned to discover how your headphone cables hit
the mark that I ended up purchasing another set of 800's to enjoy in my
bedroom system. Thanks for great aftermarket products that perform
extremely well and provide an exciting dimension to music which I have
never experienced before."
"I've been so
anxious to write back to you after experiencing the great boost in sound
quality with the addition of the Stefan AudioArt E-Series headphone
cable for my HD600's. This cable really provides serious improvements
and I just can't stop going back to all my favorite recording to listen
as each sounds so much better as if I was hearing them for the first
time on a very sophisticated system."
"Your master plan for headphone
systems is turning
out to be quite an epic event as the combination of each step has opened
up a new found level of sonic bliss. Instruments and vocal passages now
sound so real like the musicians are performing live right in front of
me. The Endorphin HD650 headphone cable, power cables and IC's along
with Mapleshade platforms for my components are now the most important
aspects of my system. Without these essential workings, I would still be
hearing lackluster sound form a very good set of components."
"The combination of stellar workmanship and
stunning sound quality of your VOICE headphone cable has made my musical
experiences with the Sennhesier HD800 headphones an absolute joy."
"I am still working on the detailed headphone system improvement plan
you sent me a few months ago and so far I am very impressed with the
results. The E-Series HD650 headphone cable was a great start as it
really does provide an extensive and complete refinement to their
performance which I could now never live without. Thanks for offering a
product that performs as no other headphone cable I've tried has come
close to the E-Series performance and providing me with such
comprehensive help towards overall system improvement."
"What a great addition the Endorphin headphone cable is to my Denon
7000's. The purity of sound delivered through these beautiful headphones
is astonishing! Everything aspect of the music is refined to such a high
level and I never suspected a headphone cable upgrade could provide such
a big jump in sound. My headphone listening is now on the same level as
my Sonus Faber's. The same holds true with my K701's with your
newly installed Endorphin, I just can't say enough great things about
"If it wasn't for your long a very detailed email responses to my
questions which contained excellent tips improving the performance of my
Sennhesier HD600's and accompanying gear, I would not have made the
investment in upgrading my power cables to your Endorphin's. These
babies are the real deal as they have breathed new life into my system.
They have provided strong, smooth bass and lifted the veil from the top
to bottom. Best of all, the mid-range the 600's now deliver is just
outstanding. Your Endorphin power cables truly do offer a great
performance upgrade and are so well designed I now do not have to battle
with big heavy power cables that only offer minuscule sonic
"The Sennheiser HD800 with your E-Series audiophile headphone cable has
a synergy unlike any of the other cable upgrades I've tried. The
improvements are not subtle and the extra money spent is very well
justified. You offer a great product along with excellent advise and I
am grateful for your honest and patient approach."
"I was so overwhelmed by your Endorphin HD800 headphone cable after
completing my own headphone cable shoot-out. Your verbal description of
what I would expect was honest and dead accurate. The Endorphin is in a
league of its own as headphone cables by ALO, Cardas, Moon Audio,
Hyperion, Oracle etc. are all poor performers in comparison as none of
them deliver distinct, pure, airy music through the HD800's. In addition
to the Endorphin's advanced performance, it displays a superior look and
feel like no other cable I have ever used."
"Your Endorphin for the HD800 headphones is quite amazing striking-up a
wonderful balance with sound so pure I never would have expected this
level of performance from
a headphone setup. The accompanying application of the mapleshade
platforms and your Endorphin power cables just makes it even better with
greater transparency, dynamics and realism. These steps you recommended
improved my rig 100% and I
am very thankful for your honest, thoughtful approach which is unique
and most importantly the best advise I have ever implementing."
"Arrived yesterday and the E Series HD650 has made the listening
experience much more enjoyable. First thing that jumped at me was the
cable ‘centered” the stage much more. I had thought the stock sound was
off a little left and using the E Series no such balance issue, in
addition of course to a much deeper heavier bottom and better sparkle in
the top end. I have only 5 or 6 hours on it but the sound is what I was
looking for – if it gets any better I won’t get much sleep."
"After two week of blissful listening with the two
Endorphin PC's replacing my old PC's, I am still in awe at the
improvements in detail, clarity and openness of sound. Wonderfully
effective product and one I never would have looked to for such hardy
"The cables are great ( Endorphin K702 and E-Series HD650) and not even
broken in yet. I cannot described in audiophile terms but everything is
opening up. Can't wait to hear them broken in and with my new gear."
"What a nice improvement you guys have made to
the E-Series HD650. The new soft look and feel is great and the music is
more transparent and exciting than my older Equinox with the HD650. I'm
hearing things that I just did not hear in the recordings before and
everything just seems more musical and enjoyable. I'm impressed and
admire your approach to continue the enrichment of what was
already a great product."
"Pleased to say I took
delivery of my new HD800 cable on Friday and my initial thoughts are
good. Very good. The physical appearance and build of the cable really
are first class, as was the packaging for shipping. Sonically the cable
provides everything the stock cable lacked. The at times painful,
dominant treble has been tamed and taught tuneful bass can now be heard
in the recordings. The best comment I can make is that it makes me want
to revisit all the music in my collection to hear the recordings as they
should have been when I first had the headphones. Unfortunately for the
last good few weeks I have had to deliberately steer clear of certain
CDs that tend to be 'bright' as I knew the stock cable would be
producing treble to make me wince should the volume be turned up.
Everything your website claimed regarding the cable's performance has
certainly proved correct and I am pleased to have made this choice over
other alternatives. Thank you for your excellent customer service and a
product to match. I am hoping to have many years happy listening with
the new headphones and cable so I am unlikely to be ordering further
goods from you for a long time. You will however be highly recommended
to anyone I come across looking to get better performance form their own
"I thought I would let you know that the cable
was delivered yesterday, thanks for your excellent communication and
"The impact of the numerous
improvements the E-Series has had on my Sennheiser HD800 listening
endeavors is nothing short of astronomical! Stunning NATURAL detail,
smooth captivating midrange and full solid bass all which fulfill my
demanding requirements for perfect headphone delivery. It is plain to
see you have put a lot into this cable as the look and feel just make it
all the better. Can't thank you enough for your exceptional product."
PS. the 800's would have been returned if I had not given your cable
solution a try."
"You guys have always been about
quality and great sound. I found that out years ago as I've been using
the Equinox with my HD600's with wonderful results! Now with my purchase
of the Senn. HD800's I knew just where to turn to fix the disappointing
sound of these beautiful new flagship headphones. Shocking thing is I
never expected the level of improvement from your Endorphin
cable which has resulted in performance far beyond the HD600/Equinox
combo. Thanks and any news on a new cable for the AKG K1000's?"
to send you this brief email. I received the Endorphin cable this
afternoon. Now I must say that hearing the HD 800's after the GS1000's
and HD 650's was a revelation. Even straight from the box I could have
lived with the sound without further complaint, so I really was not
prepared for, or expecting the utter transformation that took place
after I connected the Endorphin cable. The sound is truly heavenly, and
neither unit is 'burnt' in yet! Congratulations on developing such a
wonderful product. I will comment further in a few weeks, after the run
"Although I've used headphones
for years as my primary source of audio entertainment, the purchase of
the Sennhesier HD800 headphones was my introduction to the world of
high-end listening - so I thought. With the many agreeable aspects of
this flagship headphone I was very disappointed with the overall
performance. The tool that unlocked the sheer audio beauty dormant
inside these wonderful headphones was your Endorphin headphone cable. I
was so stunned to discover the magnitude your cable had on the music
delivered by the Senn. HD800's that I now will begin an overhaul of my
system by strategically replacing all the power cables and interconnects
which will be based on your recommendations. Thanks, you have opened up
a world of wonderfully rich and genuinely exciting music delivered via
headphones - a world which I never thought existed!"
I genuinely doubted that a headphone cable could make much difference,
especially when the HD800’s treble was so pronounced with the OE
cable, but the E-Series has brought the tonal balance beautifully into
line! My jaw hung open for the first few minutes. The E-Series cable
brings out in the HD800 all the virtues of the HD650 while preserving
the HD800’s open, airy presentation—and providing substantially more
fine detail than the HD650. Well done! Looking forward to hearing what
the Endorphin cable can do for the HD650."
"I received the
cable today and I want to return to you my evaluation review coming
after 3 hours of serious listening. Really exciting things happened
today when I connected my HD800 to the Endorphin cable, it absolutely
blew me away with first music accords and to be honest, it was surely
beyond all my expectations. As day light against night it is clear that
there is no needs at all to compare the stunning musicality of new
Endorphin HD800 headphone cable with good sound of stock.
Powerful punchy bass with excellent depth and extension, warm and
detailed middle with brilliant balance to low and high frequencies and
finally, emotional tremble like you are a part of great performance… my
friend, everything comes to life. I was ready to investment
a lot of time and money to find the
absolute best combination of
high-end components replacing source, amplifier, interconnect hoping for
the best, so-called sound-per–pound ratio but was lucky to discover that
the dedicated Stefan AudioArt Endorphin headphone cable was the key to
delivering the most
remarkable effect on the ears when used with the HD800's. Personally, I
would thank James for his many valuable comments and recommendations. As
one of your customers had already stated I also would be very glad to
take my hat off ...Great for you!”
in the process of upgrading my headphone rig and have already put into
place your Endorphin HD800 headphone cable and the associated power cables
for my source and headamp. I just wanted to let you know that I have
learned more from your extensive answers to my many questions then I
have from all the other combined responses from several other
manufacturers and dealers. I am also astounded at the enormous
improvements the Endorphin cables have made in comparison to some other
options I earlier explored. So, as you might expect, your remaining
suggestions and product solutions are at the top of my list and I will
soon engage in the process of ordering more of your wonderful products.
Thanks for disseminating honest and cost effective steps to unlock the
potential of my components and your exceptional customer service.”
"The E-Series cable arrived yesterday. It sounds
great! Thanks very much for your careful restoration."
"After weeks of research which
included dozens of emails and phone calls to several manufacturers, it
was easy to determine that your company is the most knowledgeable in
this new found headphone hobby of mine. You guys go all out answering
questions and concerns in such detail that I thought I had gone back in
time to the day when product / field knowledge and customer service were
the top priority. I will soon receive your complete high-end headphone
system cable set and get back to you to share my experience. Thanks for
"I'm a Mapleshade product user so felt comfortable
with the format and suggestions on you site. After delivery of the
Endorphin for my HD800's I was startled to discover the huge step up in
the performance of these headphones Not only is the Endorphin the cure
for the stock cable decease which now I can clearly identify as the
culprit of the harsh, grainy treble, thin midrange and under developed
bass, but it is the gateway to pure shimmering treble, warm articulate
midrange and clean powerful bass! My compliments on designing an
attractive, comfortable, high performance headphone cable."
"Every aspect of my HD650's took a
sharp turn for the better - no - way better after I connected the
E-Series. Now I wasn't going from the Senn. stock but from the Zu Mobius
so this whole experience has been a real eye opener in the sense that
your cable is quite a step above the other aftermarket offerings. Hats
off to a great product."
"Just want to let you know the my HD800's were ready
to go back in the box for return until first listen with your E-Series
headphone cable. Instantly everything was set in balance. The delivery
from whatever recording I'm listening was now a pleasant experience
conveying a naturally open, detailed and warm picture of the music. I
could go on with the list of improvements but I'll just end with this
important note - your cable is the perfect match as it beautifully
comments the look and performance of a wonderful headphone I almost did
"Even though I knew
after your first email reply that I had come the best place to purchase
a headphone cable for my HD800 headphones, I never excepted such a
wealth of valuable information regarding headphone system components in
the emails that followed. With your sincere efforts I have reached my
goals and could not be more satisfied. Thanks you for your time,
integrity and dedication."
"Yesterday if I was told that there was a headphone cable that would
completely correct all the issues I have with my Senn HD800's and
deliver the music with a breath taking rich quality I would have
laughed. Well why not. I tried other headphone cable upgrades in
the past and was left disappointed. But your Endorphin is a keeper and
then some. Great look, feel and the sound out of my HD800 is absolutely
drop dead inspiring! What a great product! Thanks."
"First thing I have to say, is that I never imagine how a cable could
change in such great proportion, the sound of my headphones!
VERY HAPPY because I now have all the qualities I research for in a good
component - I do not consider the Sony MDR SA 5000 and ENDORPHIN
headphone cable as two separated units but as one single component.
Smoothness is very important to me for my listening comfort, and to
believe that what I am listening to now is a live concert. I am always
shock by instrument's smoothness and with the ENDORPHIN my MDR SA 5000
give me much more smoothness than I had with stock cable. And for me
that is a real pleasure. Soundstage has widely improved, and it is very
easy for me to immerse myself in the music. Distance and air are
amazing! Detail, transparency, bass and voices are absolutely wondrous
and magical. I think it's important to specify all those improvements
are IN GREAT PROPORTION. Now my listening sessions are filled with
pleasure, delicacy, sensuality, emotion and joy. I have learned a lot of
things about SONY MDR SA 5000 with the addition of the Endorphin
high-end headphone cable…… My equipment - MDR SA 5000 / ENDORPHIN,
DARVOICE 336 SE/ NOS RCA 1966 6AS7G / SYLVANIA 6SN7 / JADIS EVOLUTION
TUBE player is a wonderful combination as they reveal all the
qualities this head-phone is capable of. Congratulation, James, for this
wonderful cable and thank you for making it possible for me to access
this magical musical world."
"James, thank you so much for your advise on cables
and vibration control. I took your lead and did the upgrades in the
order you suggested slowly over the past 6 months.
The process was truly enlightening and now I understand why you stressed
that your headphone system cables and the mapleshade cables and
vibration kits are very important components in any system and have the
biggest influence on the other components and the entire system as a
whole. In addition, the modifications you suggested for the HD650's made
everything even better. On doubt you saved me hundreds and maybe
thousands as now I have no desire upgrade my headphone
amplifier based on how satisfied I am my system transformation."
"For months I've contemplated but
hesitated sending the money on either the E-Series or Endorphin upgrade
cables for my HD800 headphones. Up until now I have not been satisfied
with the stock or the other aftermarket headphone cable I purchased or
tried. Well after careful research I decided to go with the Endorphin as
it seemed like the option that would give me the most improvement (Voice
excluded) based on my system of components. After several weeks of
serious comparisons with the stock and other lower cost headphone cable
upgrades, I can honestly report back that this cable is well worth every
penny. Nothing I used came close to the look, feel, build quality and
most important sound quality of the HD800/Endorphin integration. Thanks
for continuing to advance the look and performance of headphone cables.
Without your technology I would still be experiencing mediocre
performance from very good quality components."
"I have always regarded your headphone cables
(including the recently purchased Endorphin power cables) superior to
all other headphone cables on the market. That said,
I never got around to organizing and sending back my comments until my
latest purchase of the Endorphin headphone cable for the HD800's
inspired me to do so. And inspired might not be a strong enough term!
The Endorphin cable mated with the Sennhesier HD800's has completely
opened me up to a new dimension in headphone quality which includes a
strikingly beautiful appearance unlike no other headphone/cable
combination I've ever used or seen anywhere. This combined sound
performance tops my well love R10's. I'm going to put together the
another high end balanced headphone system in 2010 which will be built
around another pair of HD800's. So I will be back for another purchase
as I will be selecting your Voice headphone cable for completion."
"I just wanted to let you know that I got the umbilical for the BA"
(Eddie Current Balancing Act). " All is well. It's hard to believe the
BA can be improved upon but it is responding to every change thrown at
it. The SAA Voice HD800 re-cable is simply amazing on the BA. The
umbilical also brought a very noticeable improvement. Although not
nearly on the same level as the HD800 re-cable, your umbilical cord
removes a layer of grunge and the music seems faster without any edge to
"Hello James, I am pleased to inform you
that the package have arrived a few days ago. I have installed the
Endorphin cables in my system and was really impressed how significant
the overall improvement in sound was. Of course I anticipated better
sound from these cables, though I didn't expect that the effect would be
that great. I am very satisfied with their performance so far. Thanks a
lot for these great cables!"
"I've been in the European recording business for over 20 years and with
what I consider my highly trained ears, I have never listen to my HD600
headphones with such satisfaction until after replacing the stock cable
with your E-Series upgrade. The differences are striking and I now must
get the word out to my colleges and fellow engineers."
"In comfort and performance the Endorphin is so much
more advanced than my collection of accumulated aftermarket headphone
cables. I can now clearly see that this purchase is money well spent and
in the future I will stay away from the "fast food" headphone cables."
"Regarding performance and
aesthetics, your VOICE cable is an absolute work of art. I now have
complete fulfillment in my sound endeavor. Thank you."
"The Endorphin umbilical with the B52 is a real eye
opener. Thanks for curing this important and unrecognized area in my
system. Tube sound is now faster and more dynamic with just the right
amount of warmth." Be back for the Endorphin power cables soon."
"Just finished breaking in the new
E-series with my HD800's. Now music is an absolute joy through these
cans with the cable upgrade. All my complaints regarding the HD800 have
disappeared and now I know it's the stock cable and not the phones. Now
I can sleep at night. Thanks for curing my insomnia."
"It was a shock to
me at first listen after I installed the
Endorphin power, interconnects and headphone cable to my ZD / HD800
based headphone system setup. What I had come to realize after a few
days of intense listening was that even though I had selected some of
the best equipment available, it was severely compromised by the
cabling. Your complete headphone system cabling offers serious
improvements and I would like to especially note the Endorphin is an
absolutely beautiful headphone cable which looks incredible with the
HD800's. Thanks for your time educating me via the detailed emails and
"The Endorphin attached to my HD800
headphones has proven to be an enormous transformation. I did not
imagine that at this level of headphone (price and quality) there was
going to be this much improvement. Years ago I was blown away after
connecting your Equinox to my HD600 (after very disappointing results
with Cardas, Zu and Moon Audio cables) and now you guys have once again
proven that you know headphones and possess the expertise and skill to
produce the best headphone cabling available!"
"Absolute Magic!!! This is my experience with the
Sennhesier HD800 and the Stefan AudioArt E-Series cable. This is truly a
combination to die for as every bit of music is in tremendous balance
and all the riches of the music displayed. Thank god you left Sennhesier
to take on this task!"
"First I would like to thank you for
your quick shipment... I have had my HD800 with your E-series Noir
Audiophile headphone cable for a while and have had about 100 hours of
burn in time. I listen via Esoteric SA60 / Grover single ended / Grace
902 / E-series Noir / HD 800. This combination is truly fantastic. Well
recorded SACD:s is in a league of its own through this combination. I do
not understand how your cable can improve the sound of the headphones as
much as they do, and why a high end headphone like HD800 is standard
equipped with a cable that holds back so much of its potential."
"Hello, I am a French audiophile and I just got my
brand new SAA
E-Series for HD650 and the results are HUUUUUUUUUUUUUGE ! I want
to thank you so much for your work, you (and of course your team) are
amazing, I love you :) Great job guys !"
"First of all let
me tell you that I am old music lover regularly attending concerts and
opera house. I spent the last 30 years playing with traditional domestic
stereo equipments, building in time, a system which I enjoy very much.
That said, I am completely naïve to headphone world. Lately,
I decided to explore this new area of domestic listening prompted by the
very interesting results obtained with a ipod - portable amp - iems
combo. Once I decided to go for HD650, I understood that you should also
go “balanced” and after a few search and forum chat, SAA E-Series imposes
itself as the best way to go. My comments therefore apply only to the
comparison with the original single ended cable. And to be fair it is
more a comment on single ended versus balanced Senn. It
is hard to believe that you are hearing at the same headphone!
I know I am the last one of a long line
of HD650 owners, but the difference is stunning: a
very good headphone become a masterpiece: gone is the dark, “closed”
character of the original single ended HD650 with the relative
prominence of the bass line; you get a fantastic grip on the bass and
the sound open up, sparkling but never becoming fatiguing and retaining
a sovereign musicality. As far the soundstage is concerned (as hard it
is for me to get used to this new dimension), one passes from a vague
“in your head” imaging to a believable space in front of you with pin
point imaging and some air around instruments and singers. But most
important is the fact that for the first time I can listen to music for
long time without any sense of “missing something”.
No, listening to my system with the speakers still
remains my primary source of domestic music, but now I can understand
why a lot of people are perfectly happy with cans avoiding a lot of
troubles and saving a lot of money."
"I wanted to get
back to you and tell you how much your E-Series cable has re immersed me
in music. While I could agree with most of the descriptors I've read on
your site , it is the emotional impact and sensuousness of the music
that the cable reveals that makes me yearn for sitting in my study
with music on. Like others I was so impressed with the AKG (K702's) on
their own that I could just barely imagine improvement- it far exceeds
my imagining. Thanks for the good work."
thanks for your reply. Your customer service is really prompt and
If I ever should get tired of my job maybe you'd like to be a serious
dealer of your products for all the southern European area. Many people
should really know HOW MUCH they can improve their headphone listening
experience using your cables. I'm a former audio mastering engineer. I
was skeptical at the beginning. Now I'm a believer. For sure I'll buy
very soon another cable from you for my other pair of Sennheiser HD600."
Sennheiser 650s sound great. With the addition of the
E-Series cables from Stefan AudioArt they sound superb!" Bring
your Sennheiser 650s to their full potential with the E-Series cables
from Stefan AudioArt!"
"Just want to
stop and write how much I love the
E-Series 650 cable I bought from you guys. This cable has improved
every aspect of my 650 headphones. More detail, eliminates the recessed
midrange and adds no detractors. I can’t find one single bad quality
about this cable. Just goes to show that SAA is passionate about their
products and it shows in every aspect of my purchase from the sound to
the look of the cable and even the packaging. Very nice work!"
"Thanks for getting me my GS1000's back so soon. I received them
on Sunday, and thought that I would only play them for an hour or so but
ended up playing them the whole day! I mainly run my headphones through
a Ray Samuels Hornet for portability but I decided to plug it into my
home system, and WOW...Your cable, with the GS 1000's plugged into a
Cary 300 SEI with a
Cary 303/300 is quite
frankly unbelievable. A while ago, I bought a Sennheiser 650 with the
Cardas cable, and wasn't really impressed. I really didn't hear much of
a difference between the stock and upgraded cable. In fact, I thought
the Cardas sounded a little sharp compared to the stock cable. I was
afraid I wouldn't like the sound of the E-Series but after my dad
upgraded his, I decided to give it a try based on how impressed he was
with the cable. I sent my turntable in for an upgrade but once I get it
back, I can't wait to try it with my upgraded GS 1000's. I know I
haven't broken them in yet but let me tell you, I am perfectly happy
with them now. I tried my CD with Dave Matthews and Tim Reynolds Live in
and man, the acoustic guitars have NEVER sounded so real. Seriously,
I've been to Hi Fi shows, I have a home system, etc. It was almost scary
on how...organic it sounded. And what really impresses me the most is
how everything really has its own "space" on the stage."
"Some say that
switching cables can't really make any difference on the sound. I
learned that that was false by switching the 600's cables with 650s. It
made music have more impact and deeper bass, but lost some of the
detail. Trade off. But I just got the E-Series and WOW! You weren't
kidding when you said that these would be the most significant upgrade.
Absolutely no trade-offs here. These sound like completely new
headphones. These sound like what I expected the HD600s after investing
so much money in them. I always felt like a strip of sound was
missing... Like I was at a wonderful concert, but listening to the music
behind a thin wall. Now I'm right in the middle of the music. I'll write
a more formal review after giving them more listening... I've only used
these for about
20 minutes and the improvement is astounding. It put the 'soul'
back in the music. Wonderful product!"
"I have posted an initial review
of the Endorphin Ribbon Power
Umbilical Cable at
is under the Hi End Audio title and is on page 23 of the thread "Zana
Deux Tube Rolling". The cord gives a wonderful improvement to the Zana
Deux. I believe it's improvement to the Zana Deux is greater than your
fine Sennheiser 650
cable to that headphone. Certainly having both in the system is
synergistic. I have not tried any sort of A-B comparison with the stock
cords. The improvement are immediate and obvious. I will try the
power cords after a have more listening time on the current set
up. Feel free to use any of my words about your cables."
your cable for my Sennheiser HD600. I've followed the instructions on
the sleeve inside the box and everything went smooth. Oh boy! What a
change in the sound.
As a former audio mastering engineer at the beginning I was skeptical.
But now I can clearly say that it's like having a 3 way full range
speaker around you head! Mids and high frequencies are more open and
precise now. Transients attack is also faster and bass response is
clearer. This cable is highly recommended! I just want to say thank you
for this wonderful opportunity. Feel free to insert my comments on your
ABSOLUTELY no more doubt in my mind regarding your Endorphin ribbon
headphone system cable set! Such beautiful improvements in the bass and
soundstage and an added rich presents in the overall sound. I've
searched for years trying different component combinations and never
even came close to such improvements. And as far as the power cables,
I've never even considered this as an option for improvement. But when I
put back my old cables, I just couldn't believe the step-down in sound.
You guys have truly addressed the problems in headphones systems and
come up with wonderfully effective solutions. Thank you from the bottom
of my ears!"
"...an the Endorphin power cables have
got my endorphins working overtime! never excepted this much improvement
from a power cable. Deep rich bass and a much bigger soundstage are what
really stand out in most of the material I listen to and my old AQ power
cables are being demoted to my computer equipment. I've just want to
add, I've had such great success with your headphone cables and now with
the power cable upgrade, I can't tell you how delighted I am with the
continuation of your quality products!"
"If I had expected
to get only half of the long list of improvements the E-Series cable
introduced to my HD650's it would have been money well spent. So I'm
sure you know where this is going as you have probably heard it a
million times before and you will probably hear it over and over for
years to come. You have tapped into to the heart of what makes the HD650
sound like no other headphone on earth. These cans are just phenomenal
thanks to your E-Series cable which has finally made listening with
headphones a true audiophile experience."
You are right! Nothing beats listening
to headphones that deliver the music from outside and around the ear.
I've put my IEM up for sale as I now enjoy my portable listening with
the HD25's with the E-Series Lite. They're much more comfortable, organic
and musical. No more ear pain from having IEM in the ear for too long -
Thank you, Thank you, Thank you!"
"I have to admit,
I really doubted your prompt replies to my many questions regarding the
Endorphin ribbon power cables performance. In fact, I never thought I
would really hear any difference, but with the money back guarantee I
was still was curious and had nothing to lose. Well thanks, this cable
really does improve the sound and just as you described! As I
continue this wonderful sonic endeavor of high end headphones I will now
pay closer attention to smaller, customer services oriented companies
like yours as your products (I also have your E-Series for the HD600's)
offer real solutions."
"The conversation we had over the phone
a few months ago took a while to sink in. It was the part where you had
mentioned cables, headphone, power etc. not being a very exciting
component to purchasing. You went on to mentioned that most users go for
the glamorous purchases like headphones, amplifiers etc., which only
result in minor or even no improvements to the overall sound making a
large investment with little or no return. I decided to go with your
direction and it has really paid off. My 650's SING with the E-Series
headphone cable and it really looks great in comparison to the stock or
other after market cables I considered. And, man when I added your
Endorphin power cables to my Headroom amp., another big step in improved
sound. I have a whole new respect for my components which I once thought
were the cause of unbalanced and inconsistent sound. As you advised, my
next step will be addressing the vibration in each component. Thanks for
honest and effective advise."
"It all makes perfect sense now, but before I forget to mention, the
E-Series cables for the AKG 1000 headphones is spot on. What
really prompted me to make the change
is that my very expensive speakers do not come with a cable attached and
if they did I'm sure it would leave much to be desired to the overall
sound. I've worked in related fields where the cost of good
cabling and similar products just adds to much to the cost of the
overall product pricing it right out of the market. But that all said,
my K1000's are now ship shape and they have exceeded all my expectations
and are now my first choice when engaging a listening session."
"You probably don't remember me, but I sent my Grado RS-1 headphone all
the way from Spain for installation of your wonderful E-Series cable.
What a beautiful job Grado Labs did with the installation and the sound
of the RS-1's with the E-Series has filled my head with the most gorgeous
musical sound on this planet. Thank you for a fabulous product."
"For the past year and a half I've enjoyed the exquisite improvements
your E-Series cable has brought my HD600's. But I'd say with the addition
of the Endorphin power and IC cables to my system the performance has
just about doubled! I now have no need to entertain the idea of
purchasing a $1500- $2000 headphone amp. I once thought I needed to get
to this level because after several sessions auditioning headphone amps
in this price range, I never heard these kind of improvements. Thank you
for producing products that truly deliver "beyond expectations" results
and for making a believer out of me. This also extends to the ergonomics
of both the power and IC cables as they are light and flexible and truly
a pleasure to work with."
“Your E-Series RS-2 product is truly remarkable, I am so happy you
decided to choose this endeavor. I just want to thank you for having
such a wonderful product. Oh my goodness, I’m sorry to rant and rave and
ramble. I am so thrilled; it is so close to live, real. The detail, the
micro dynamics, every superlative that I could possibly think of that is
positive applies to your cable. I am such a happy camper and I
appreciate your work greatly. Thank you so much”
only connected the amplifier cable and I listened to a CD that I don't
weary myself to listen, a treasure of songs and music made by Jordi
Savall : Villancicos y Danzas Criollas (AliaVox of Sony) I doubted to
hear any difference and I immediately felt a shock: it was incredible,
it's not useful to wait a hundred hours ! The average frequencies are
not aggressive any more and the sounds are more natural, the low
frequencies are fuller and detailed, the high frequencies are softer and
removed of distortions, even on strong level. The marvelous singers are
there in the living room, I hear them breathe, the instruments played
around me, each one in its place, I hear their vibrations and I perceive
the thin reverberation of the place of recording, I listen to the divine
Mrs. Montserrat Figueras
and my heart is tightened, I cry... I will tell you a secrecy : because
of you I love her still more ! I don't think of connecting the headphone
cable, I'm too afraid to loose this irreplaceable instrument. I knew
that the K1000 is very good; thanks to you I know today that it is the
best. I congratulate you for this excellent result and I thank you very
"Contrary to my past experience with
power cables, the Endorphin has proved extremely beneficial to the
overall performance of my system. Improvements are comprehensive across
the audible frequencies, but what is notably impressive is the new
addition of deep, tight bass. Thanks!"
"....and headphone listening was always
a lesser musical event until I purchased your E-Series HD650. Now I'm
reaching for this incredible combo as my first choice as they deliver
great warmth, detail and a unexplainable richness."
"My RS-2's are singing a sweet song
after upgrading to your E-Series headphone cable. Spacious, warm,
detailed sound with awesome bass is now the final product from every
section I play. Thanks for a stellar product!"
"How could a simple change from the
Sennheiser cable to the E-Series on my HD600 make such a big difference?
I have sent the past year and a half spending $$$ upgrading and the
headphone cable change has by far put the most magic in the music. I'll
be back soon to try your Endorphins........"
"The E-Series installed on my Grado
RS-2's has improved the sound to mind boggling proportions. Now the
music just floats around my head as if the headphones aren't there and
the bass, midrange and treble are all in perfect balance. One great

realize the E-Series HD650 headphone cable offered the single biggest
improvement I had ever experienced from an upgrade. Dollar for dollar an
"After connecting the Endorphin ribbon
IC’s between my CD player and headphone amp. it was like someone scraped
a heavy layer of film off the musically picture. Great clarity, warmth
and bass to die for! Next on my list the Endorphin ribbon power cables.
You guys are the true authority on headphone systems – many thanks."
"You guys were not exaggerating, the
Endorphin power cables delivered HUGH improvements to my headphone
system. It was like when I first connected the E-Series to my HD650's -
Pure Heaven! Thanks for offering another incredibly product which offers
major sonic improvements for us headphone junkies."
"Your E-Series for the
GS1000 is the missing link to wonderfully detail warm and spacious
sound. Now everything falls in place and record and CD (yes CD!)
collections are now by far the most musically satisfying."
"The addition of the E-Series cable and the removal of the ear speaker covers has transformed my AKG K1000 to now
without a doubt in my mind are the best headphones available. My top of
the line Stax system is no longer champ as the E-Series cable has allowed
the K1000 to surpass all my other headphones with the most incredible
balance of bass, mids and the most wonderfully natural detail I have
"The E-Series headphone
cable is absolute MAGIC. If I had the opportunity to use to the HD650's
with the stock cable again, I just couldn't do it!!!!"
"I received your wonderful
E-Series cable for my HD650 Senns and have been playing them
nonstop to burn in since receiving and my impression after about 12
hours of burn in is, WOW. The music is so much more involving-words are
hard to find but so far I'm stunned at how it just seems to pull the
notes from the distance(b4 the E-Series) to the forefront (with
E-Series)! I'm already very satisfied-already money well spent. My 650s
sound like they are worth at least 500.00 more! Your cable has already
exceeded my expectations and burn in is far from complete."
“Detail, warmth, beautiful textures and soundstage,
that what most impressed me about the E-Series with my HD650’s. I could
go on and on with a long list of improvements but I got to get back to
listening. Upgrades for headphones do not get any better than this. Many
“Improvements beyond belief, the E-Series cable is a true audio
“OK, now I know why the wait for the E-Series cable is so #*@%$*# long –
it adds out of this world performance to my HD650!!!! To ease the pain
of the wait, I listened to the 650’s with my old ...cable, but now I can
only listen with the E-Series connected...."
“Owning a very modest headphone setup and having a limited budget, I
saved some money and sold some old equipment to purchase the E-Series
cable for my HD600’s. I just want to let you know your product performs
far beyond my expectations and I never imagined experiencing music at
such high quality through headphones.”
“I’ve read plenty of accurate reviews on the web as to how wonderful
your E-Series cable is sonically. But, I just had to write in and
compliment those reviews by adding how beautifully constructed and
flexible it is as well. I think this is an important point because
the other aftermarket cables I’ve auditioned do not come close to the
pleasing aesthetics and comfort of use you guys have incorporated into
this phenomenal headphone cable.”
“The combination of the E-Series cable and the HD650 is an absolute
masterpiece. All the colors and textures so to speak, are right as they
should be. The vivid and sharp, yet organic canvas the combo paints
creates an addictively pleasant listening experience. I’m going to have
a very hard time going back to listening to my speakers which I have
spent 10 times the amount of money on.”
“The E-Series K701 headphone cable has transformed by new system lead by
the Cayin HA-1A into a sonic Valhalla. Now with about double the
soundstage, the music comes across in a much more balanced and natural
fashion. The lows, mids and highs are presented in harmony and the bass
is well represented. AKG’s Richard Land did a beautiful install job and
in a very short time. Hats off to the people at SAA, as I am grateful
for the time and effort they applied to their products (I also own the
E-Series for my HD600’s). This type of excellence from a company is fast
becoming a thing of the past.”
“My skeptic, highly unlikely attitude towards the E-Series headphone
cable improving my HD650 to a much higher degree than the other after
market cables changed the moment I gave it a first listen. Your cable
really does wonders for these headphones and would still be well worth
the upgrade at twice the price.”
thought I died and went to headphone heaven after I connected your
balanced E-Series to my HD600’s. No other component offers such
phenomenal improvements to the Sennheiser’s and believe me I’ve spent
thousands of $$$ in my attempt to improve them. Thanks for a great
product that truly performs to this crazy audiophile's incredibly high
“After using several aftermarket headphone cables
...., I can accurately testify that the E-Series
is a major step-up from these cables and takes the HD650’s and HD600’s
to the absolute pinnacle of performance. Many thanks from an extremely
satisfied die-hard audiophile.”
“I’m extremely impressed with
the E-Series headphone cable as it offers such striking improvements to
an already very sophisticated sounding HD650 headphone.”
“My jaw dropped to the floor after connecting the
E-Series to my HD650 headphones and now the only way to close my mouth is
to stop listening to music with the E-Series connected or go back to
using the stock cable.”
“My 701’s with the E-Series
audiophile headphone cable is just about broken-in and I wanted to share
my before and after impressions. Quite a significant improvement has
been made to the soundstage much to my surprise. With the E-Series the
701’s are WIDE open and this makes the music much more realistic
especially live recording. Before the addition of the E-Series, the 701’s
were a bit thin, but now there is a greater sense of balance and the
mid’s are really smooth. Another big surprise is the incredible clarity
and definition the 701’s deliver with the E-Series installed. This is
very noticeable with vocals which are huge with that “right in your
head” realism. Overall the E-Series is a must have component for the
701’s if you truly want the best performance. Thanks for the great
“I just finished installing the E-Series to my AKG
K701’s and my first impressions are that this is a wonderful improvement
to the definition, detail and sound stage. I would have never believed
that a considerable amount of veil could be removed from these
headphones with the addition of the E-Series and again that huge increase
in sound stage. Also noted is the nice improvement in bass with a much
smoother midrange. Thanks for another great product (I have the E-Series
for my HD600 which is absolutely incredible).”
“The performance of my AKG
K701’s is incredible after installing the E-Series cable. The
installation was smooth and the instruction were very good with the
inclusion of the AKG technical sheet.”
"My use of the cable is only
audiophile, not professional. My comment is: great improvement for the
HD650. Indispensable for serious listening."
"The E-Series HD650 Noir is the only headphone cable
for a true audiophile. No other cable comes close to the incredible
improvements one will experience with the Sennheiser HD650 – 600 – 580
etc.,.... You guys have accomplished a great task designing a
headphone cable that offers Sennheiser headphone users such
comprehensive improvements for such a small investment.”
"Thank you, thank you,
thank you! Everything you said concerning your headphone cable is
true! I received the LE yesterday, cued up "Sing, sing, sing" from a
Telarc CD, hooked up my Portaphile V2 amp and was simply amazed at the
difference! Right from the box! My venerable 580 Jubilees's sang like
a nightingale on steroids! Attack, detail, imaging and clarity
all leaped forth with balletic grace. Cymbals shimmered, drums were
full of depth and resonance, clarinets were distinct. Details were
delivered in sweet abundance. Well, you are familiar with all the
qualities of your product. The wait was worth it!"
“The thing that
baffles me the most about your wonderful E-Series HD650 headphone cable
is that it cost me so little for the major improvements it brought to my
headphone listening systems. My Tube system (Meridian /Ray Samuels) now
“sings” with incredible realism and my solid state setup (Meridian
/Sugden) now has the most incredible detail with just the right amount
"Your Sennheiser HD650 LE E-Series cable is
awesome! I have never heard such an improvement with cables, or even
upgrading headphone amps, as I have experienced with your cable! The
improvements are stunning. Now I enjoy the 650's more than any other
headphone in my collection, by a good margin. The sound is so much more
natural and organic sounding, the bass is tighter and deeper, the mids
and vocals are more palpable, open, and real, and the highs are
excellent, more lively, and more detailed than the stock cable. Your 650
E-Series '"lifts the veil" so to speak! The soundstage also seems better,
especially depth-wise. I cannot believe the depth of the sound! I now
can listen to the 650's without becoming bored. Now my toes are tapping
and I loose myself in their excellent sound! I also had the .....
cable, and its not in the same class as yours, imho. The ...... sounds
more congested, slightly brighter, and just a tad metallic compared to
yours. I would recommend the E-Series to anyone without any hesitation at
all. A truly
first class outstanding audio product! Keep up the great
"I am the ultimate headphone fanatic, constantly
searching for the best upgrades for the three systems I use. After
auditioning every headphone cable available, I can confidently report
back to you that your E-Series audiophile headphone cable is KING. With
all the other headphone cables, I use to have to choose the one that
sounded best based on the type of music I was listening to. With the
E-Series my HD650's and 600's sound absolutely perfect with everything I
listen to. I just ordered my third one and I'm very excited as it will
complete my third system."
"Your E-Series has changed my concept that a headphone cable upgrade
can not be as effective as a component upgrade, The E-Series upgrade
surpasses my previous upgrades (source and headphone amp.) and it was
a third to half the investment. I took a chance, learned something new
and now I'm enjoying the benefits. Thanks for the honest advise."
"Ok, just purchased my second
E-Series cable for my HD540G,
yeah...I have two E-Series and don't know why I can't resist to buy it
again. The new cable sounds even better than the old one,
The sound is so gorgeous, so beautiful :)"
".... Next time I'll listen a
little closer to good old Wes Phillips before I make my purchase.
Thanks for a wonderful cable that can truly be labeled an audiophile
"....Man what magic do you guys use to
produce the E-Series headphone cable!...."
"...Your E-Series cable is pure magic with my high-end system. Thanks."
"I received the E-Series
cable several weeks ago and have been listening extensively to it. I
have compared it in direct A-B comparisons to two other aftermarket
cables: the Cardas and a Headphile BlackGold. The Cardas offered the
least noticeable improvement over the stock cable. The Headphile offered
very subtle improvements over the Cardas. I expected similar subtleties
from the E-Series, but in fact noticed a very great difference: the
E-Series transmitted the higher frequencies more clearly than the Cardas
or Headphile. Even with a high-quality solid-state amplifier, the Senn
HD 650 can sound dark; that’s just its voicing. This stronger
presentation of the higher frequencies overcomes that short-coming
without sacrificing any of the HD 650’s myriad strengths. Also, the high
frequencies do not become fatiguing (as with some headphones), but
simply more balanced. In short, I absolutely love the E-Series and am
selling the other two cables. Lovely work! I have posted my impressions
"After using the E-Series cable for one year,
I can say one thing - It impressed me. It's the best headphone cable
I've heard - my equipment being (cd player cayin, headamp gs-1). With
regard to the stock cable, there is no comparison. When I first had a
listen, I did not believe my ears because the improvements were simply
awesome. The improvements I've experienced (which cover the entire audio
Endorphin) are expanded soundstage, greater detail, 3D vocal
presentation, open and natural treble (which is non-fatiguing at high
level), midrange (which is so smooth, textured and wonderful)
and bass which is tight, well defined and extended making the music so
real. In short, I'm a very satisfied owner of the E-Series cable and I
recommend it to all.
"Goodness, what a marvelous cable the
E-Series is! My previous experience with cables (stock, Cardas, and
Headphile) for my HD 650 suggested that cables don’t make much
difference. However, I noticed the E-Series contribution immediately.
It alters frequency response slightly to make the HD 650 sound less
dark, more open and natural, yet without sacrificing bass response and
without sounding fatiguing. What a perfect balance! Thank you!"
"The results of several long
comprehensive listening sessions with your E-Series cable and my HD580's
all have ended on the same note which is "A" or an A+ which is my rating
for your wonderful cable. And what I found fascinating is that the
E-Series/HD580 combination also sounds incredible when listening to mp3's
on my laptop. It is truly one of the if not the biggest steps forward I
have taken in my audio system upgrade journey..... ......Thanks for saving me a lot of
time and money with your excellent advice."
Equipod cable is so seamless with the ipod and sets a new listening
standard for mp3 listening. Other interconnect did not offer that
natural organic sound and I can see how this could easily be overlooked
as I did not think it would make as big a difference as it did. I
can't wait until I re-cable my 701's with the E-Series in February."
"I'm in absolute audio heaven now
that the E-Series is connected to my HD650's. What I love (and still am
perplexed) about the combination is the earthy synergistic quality the
music takes on but simultaneously delivers a realistic live quality
unlike no other cable and headphone combination I've heard. I've found
my paradise and there is no need to look further."
back on all the upgrades I've initiated in the past five years I have to
say that the headphone cable was most significant. It has had such an
impact on my listening that I now prefer headphones to my speakers.
Headphone technology has come a long way, but I have to admit that
without your E-Series headphone cable the improvements are much less
dramatic and enjoyable."
"The first word that came to mind
when I connected the E-Series to my HD650's were stupendous, as
this cable has opened up a whole new level of listening which goes far
beyond my speaker based system. The improvements are comprehensive and
the other cables I've used ........ do not offer
the closure of a completely natural and cohesive sound. My comments are
based on many hours of serious comparative listening." Hats off to your
"What was I
thinking! I waited much too long to upgrade my headphone cable for
my HD650's. The improvements from the
E-Series are extraordinary! I'm still scratching my head as to how
a headphone cable could deliver such major improvements. I only wish my
new components offered similar results when the old ones were upgraded.
"Your E-Series cable is a
tube/vinyl lovers dream come true. My system is now perfectly smooth and
natural thanks to the E-Series headphone cable. ....."
" Your E-Series cable is one of the most important
upgrades I've made in my system (and I've made a lot of them) and a
classic example of a great product destine to stand the test of time."
" The E-Series headphone
cable is without a doubt the biggest improvement I’ve made to my system.
Also, thanks for your suggestions which helped guide me through this
"The balanced E-Series is just
incredible with my balanced preamp. and the description on your
website - " closer association with the impact of the music", really
holds-up and this is what I've come to realized makes the E-Series such
a great headphone cable."
"I'm a long time Beyer Dynamic DT880 user and never really thought
about a cable upgrade. After coming across so many great reviews and
comments regarding the E-Series cable, I decided to order and give the
install a try. The guide you include for the installation is good and
I took your advice and had the electronic repair shop in town do the
install. Well, I could not be happier. The improvement are right there
even before the break-in period. Richer. fuller, more natural
sound which eliminates the emphasis on the treble. Great cable for a
....." Now, your Hardwired K1000 cable is a
God-send for the AKG's. Your cable has addressed every issue I've had
with these headphone and now I'm sure I'm listening to one of the (if
not the) best headphone on the planet. Many thanks."
"I have to admit, it was quite a project to upgrade my AKG K1000
headphones to your Hardwired K1000 audiophile headphone cable. I’m not a
patient person, so for me, the 8 week wait to receive the cable was
long. Them, I had to wait another 3 weeks for my local audio dealer to
do the install. Well, going through this long process has resulted in
two positive things. First and most importantly, the cable is so
extraordinary that it has truly made headphone listening my first choice
over my Sonus Faber Cremona's. Before your hardwired
K1000 cable was installed, there was no comparison
between the two. The Cremona’s had the K1000 beat hands down in all
categories (except for the very subtle things you can only hear with
headphones and the K’s do that very well). Now, with the Hardwired K1000
cable installed it is like having the Cremona’s right next to my ear
without the room acoustic errors. The K1000’s now sound sweet and
natural from top to bottom with a bigger more realistic soundstage. The
harsh highs, mediocre midrange and slightly lean bass have been replaced
with smooth sparkling highs, to die for mid’s and a full articulate bass
response that I’ve never heard from any transducer before. Secondly,
(now that I’m in headphone heaven) I’m going to have a more patient
attitude. Why, because just by simply waiting could prove results as
incredible as your K1000 headphone cable."
I'm not one who usually follows
through with comments back to a manufacturer about the performance of
their product (and my wife would back me up on this one as she
constantly reminds me how I need to follow through with projects I start
around the house), but I am so blown away by the incredible
transformation the balanced E-Series headphone cable has done to my
system, that I just had to go against my nature and send you a response.
First off, everything about headphone listening has GREATLY improved
with an added emotional attachment to the music which is so addicting
that I end up listening late into the night (without falling asleep!).
Secondly, construction wise, the cable looks great and ergonomically
performs wonderfully. I
could go into more detail about your wonderful cable but I feel myself
transforming back to my procrastinating nature and if my wife catches me
writing this response, I'll have to complete at least one of those
unfinished domestic projects. Thanks for perfecting my system."
"Thank you for your patients and
honesty. Patients for the dozens of emails and phone calls answering all
my technical questions. Honesty for producing a spectacular product that
performs far beyond my expectations. As soon as I connected the E-Series cable to my HD600's all the
details of what you described I would experience became a reality. And
after the 72 hour break-in, I was amazed at how absolutely perfect
everything sounded. You truly are working that technical magic producing
the E-Series and I am going to help spread the word to the thousands of
Sennheiser headphone users that have settled for a lesser headphone
"I just received my Balanced XLR E-Series 650 cables and they almost
knocked me out of my chair, they are fantastic. Thanks for making them
very neutral, unlike the Zu Mobius that bite and sting my inner ear drum
with their brightness. I'm looking forward to getting my single ended
E-Series 650 cable March 18th to use on my headroom desktop unit from
you! Thanks again"
"Got the cable a couple of days ago. Been meaning to write sooner,
but any free time has been spent listening. Improvement in my 600's was
immediately apparent on plugging in the first time. Soundstage moves
back about 1" inside my head and opens up in all directions, much
greater sense of airiness. Deeper tighter bass, better defined trebles,
much more articulate and engaging mid-range. Faster transients and
better, more realistic decay. Very coherent. Wonderful product. Given
its construction I know it will even be better when burnt-in. So
impressed I've already taken steps to improve my FM tuner source."
"After 200 hours break-in, HD540G with E-Series
sound much more open & natural now. I must say this is the most natural
& expressive sound I've ever heard, I've never heard such incredible
musical sound in any headphone system before( include some $$$$
headphones) Thanks for the product & please keep up the good work ."
"I got the cables today....Wow!...I was skeptical
that headphone cables could make that much of a difference but I'm
really amazed at the improvement! I thought it sounded good before but
now I can really feel each note of the music,. Worth every penny. Thanks
installing the Stefan AudioArt K1000 headphone cable and removing the
grills as suggested in the installation instructions, I thought I had
died and gone to heaven. I can't believe the difference your cable and
the removal of the grill does to the sound. It is just as you described,
the hardware (headphones) become removed from the music and what is left
is more emotionally involving music. Your headphone cable is such an
incredible product which allows audiophiles like myself to
enjoy music on a level I never thought possible."
"I am so amazed at all the wonderful improvements your E-Series cable
has added to the performance of my HD650 headphones. Now I understand
the importance of audiophile headphone cables and realize why spending
5 times the amount on a new headphone amplifier doesn't even come
close to matching those improvements..... ."
very happy to report that after thoroughly researching all the after
market headphone cables for the HD650 headphones (which included dozens
of calls to several of the manufacturers), the E-Series has proven to be
an incredible upgrade revealing a plethora of sonic improvements I had
never though possible.
Please let me know when the E-Series cable for the Beyerdynamic DT880's
is ready, my ears are drooling in anticipation...."
......"Thanks for improving my listening experience ten fold."
"Many thanks for the E-Series cable, I would
like you to know that I think it is superb and fixes a previous (and
previously unknown of) "weak link" in my headphone setup. I run a Naim
CD5i through a Naim Headline headphone amplifier into my HD650s. I saw
your cable reviewed in the June 2004 edition of Hi Fi World (UK)
magazine and up until then had been considering buying another but
never got around to it because I thought they looked rather vulgar,
regardless of the sound improvements. I was impressed by your
employment history and liked your way of thinking once I had seen your
website. I am not by any means a professional musician (my fiancée
will certainly testify to that!), but I do attend many classical
concerts. I think that the best way to describe the improvements that
your E-Series cable has made is that previously I was still aware that
I was listening to headphones, now it is practically indistinguishable
from being at a live performance, and in a good seat too! Never before
have I looked behind me whilst listening because I heard a cough on a
live recording and thought it was somebody in the room with me. I am
sure that there are a few better systems than mine out there, but I
think you've helped me reach the limits of what my ears can hear and
my mind can believe. In a nutshell? By far the best upgrade I have
ever done. Again, many thanks."
"I've had a good listen with my new cable and I have to say that the
results are astonishingly good. It is like having a new CD
collection. What is impressive is that I can hear instruments
that I was not aware were there, and can follow them throughout a
However, the music still hangs together as a whole - the overall
effect is one of not believing I am hearing the music as the artists
intended. It is a sobering thought that probably much less than 1%
of people are experiencing anything approaching this quality of
sound on headphones. Digital radio is also a revelation. I'm not
THAT fond of classical music but the effect is of actually being in
the concert hall in broadcast live performances."
"Received your cable today. Wasn't prepared
for the HUGE difference it made. I am using the Grace 901 headphone
amp and the difference is totally night and day. Congratulations on
a truly outstanding product that I will heartily recommend to
"I'm listening as I write this email & whilst I've only had the
cable connected for an hour or so, the difference is amazing - it is,
in fact, night & day. Smoother, better control, especially in the
bottom & mid. Top end is silky, much better defined, more "air" &
depth, much better focus & sound stage, overall significantly more
listenable (not that the stock 650's are too shabby!) & just plain
BETTER. I'll send further (more coherent) impressions after a
"I have been burning in the new lead for more
than 72 hours, and while I am sure that improvements will continue, it
is now at an advanced stage of my initial impression. Soundstage and
separation have really opened out, bass instruments have become more
realistic with excellent pitch definition, and treble has clearly gone
beyond my hearing capacity (I am 61 but what I can hear must
benefit). Midrange, where most of the music happens, is vastly
improved and now very rich and transparent, arguably as a result of
the increased top and bottom extension. Also it is important to
report that a large orchestra or church organ are reproduced with no
loss of definition or soundstage. In short, brilliant!
As a side benefit I was able to hear that
channel orientation via my (excellent) headphone amp (Ben
Duncan/Hifi News Phones 01) was reversed - likeliest culprit is the
interconnect from preamp to Phones 01, which is twin RCA/Cardas/5-pin
XLR. Orientation is correct at the preamp outputs, and reversing the
Phones-01 lead corrected the problem. This prompted me to have a
listen via the standard Sennheiser lead. What a contrast! Pinched,
thin, and no soundstage to speak of - obviously to the extent that I'd
not noticed the wrong orientation. How dare Sennheiser restrict the
performance of fine headphones with such a poor lead! Makes me wonder
how much is lost between left and right cans.....Obvious answer is
HD650 with your lead as soon as possible. I'll be in touch when I can
Many thanks for such an improvement to my
listening (you can use these comments in your publicity if you wish
to, either in part or in full) ."

the E-Series cable and I'm thankful as I'm sure hundreds of others
are for your fair pricing and years of hard work and research."
"I now have spent about 20 hours
listening to my new E-Series cable since its arrival 6/1. Already I am
astounded, amazed, flabbergasted,... at what an improvement the cable
makes in what I hear from my Sennheiser HD590 phones! I would not
expect to experience such a great difference just from a cable switch.
(And, as an aside, I now wonder why Sennheiser would not use such a
cable as original equipment, in view of the huge quality boost it gives
"I want to thank you for producing extraordinary cables for the
Sennheiser HD 600s. They were easy to connect and are pretty much
broken in by now. The improvement over the stock cable is just about
unbelievable. My taste runs to complex music (string quartets, Bach
keyboard music, piano sonatas) and I am very happy with the
improvements in resolution, midrange and bass. What was once an
extremely good and satisfying sound system (Headroom Max, Sennheiser
HD 600) is now out of this world, and a lot better than my "normal"
".....I only wish I went straight to the top and
purchased your E-Series HD650 headphone cable first. Yes, I
foolishly admit, I took the more (or most expensive) way to final hear
how wonderful these headphones sound. I don't know how you did
it, but I'm finally satisfied and my large accumulation of inferior
aftermarket headphone cables are headed for ebay."
"Yes indeed the E-Series is a set of killer cables. The HD650/E-Series
combination offers such fluid musicality!!! Sacre Bleu!!! Beats
the hell out of speaker systems I have heard that cost more than an
arm and a leg."
"Oh, man! The HD-600s should
definitely come standard with these cables. I
can't believe Sennheiser is not begging you to mass produce the E-Series
them. This cable turns the Clou Red into chopped liver in my opinion. My
sounds so damn real it's scary. The soundstage is huge, with sweet
highs, and deep defined lows. The mids are gorgeously liquid with
detail. This cable is easily worth twice the asking price. My system:
Wheatfield HA-2, Sony SCD-C555ES, Audioquest Viper, and Clou Red thrown

more defined; the cable fixes the HD590's treble's unnatural metallic

K1000 cable has proved impressively synergistic with my AKG K1000

first, but after the full 72 hour break-in and several long listening

and bass is slightly more present. I can relax now when listening!"
."..... the E-Series has changed the character of
the HD-600s in a way that has recaptured that intimate enjoyment of
music that I had all but forgotten. The upper midrange glare that I
had assumed were a function of the HD-600s is gone, and they are
tonally much more even. And yet they capture even more detail. The
net result being that music is much more musical. Thanks for a
wonderful product. I wish finding a loudspeaker cable that offered
such synergy was as easy..."
"HI: WOW you guys and girls? Are great. I received my E-Series cable
today for my senn. 590s. I ordered the cable without the black cover
because of the price. Well, the cable came with the black cover with
the red tag and is just beautiful. Out of the box the 590s sound
better with the E-Series cable with no burn in yet. The bass is more
solid and the highs are more mellow and the bass is tighter. I am
burning the cable in now for 72 hours. I would really like to thank
the E-Series people for giving me the cover and such a great cable. I

superb! What more can I say! The AKG K1000/Stefan AudioArt cable
combination produces the best sound I've ever heard from a headphone
including Stax, Grado, Sennheiser, Beyerdynamic and Sony."
"Your E-Series cable is class "A" both sonically and
ergonomically.....it adds significant depth and richness to the HD600
musical delivery and the flexibility
"Hi...I received my new cable on Monday (it was a nice surprise that
it arrived sooner than expected) and have been burning it in nonstop
since getting it. I just want to thank you for making such a great
improvement to my K1000s (very apparent already even though I only have
about 30 of the recommended 72 hours of burn-in). It is obviously a very
well designed, well made, and high quality cable and will provide me
with many years of listening enjoyment. Being so new to the whole
"audiophile" experience and economics I am only now beginning to realize
what a bargain it is. "
"All the customers opinions
seemed too good to be true, but they are ALL correct!!!!! Your E-Series
cable does everything right. I look forward to listening to my
Sennheiser HD-600's more than ever !!!!! Good Luck in
your cable business!!!!!"
"First I have to congratulate you
on the nice work you did. This is indeed a very good cable. I also
have to say that I should also congratulate the guys that build the
But I think they could have done a better job with the original
cable... HOMBRE!!! Your cable makes the sound of the HD600 blow up
The first big improvement was the
"soundstage" inside my head. It changed from two dimensions to a
nice 3D, with the instruments more focused. There was a "back to
front" soundstage that I couldn't ear before in the headphones.
The mid-range was the second
big improvement. Much smoother and warmer. Voices are now much
richer and clear, without any loss of detail. Also the timber of
acoustic instruments like piano and guitar are really nice.
The third improvement is on
the bass extension which is deeper and better controlled. And
finally the treble is smooth and sweet. I've found the treble of
some CD's harsh with the original cable. Now harshness is gone.
Finally, I must say that your
cables are smooth and warm, but also very transparent and
"I just received the E-Series cables
and I must say that the wait has definitely been worth ever second
of each day. Even without burning them in the jump in performance
quality is un-believably amazing. Using the old stock cables, I used
to experience slight crackles in the playback but with your cables,
that problem has been completely eliminated. On a sound quality
level, the jump in audio quality to me is as great to the change in
musical finesse when I first purchased my headphone amp. In short,
your cables are simply breath taking! A definite must buy for any
HD590 owner! Thank you so much for your wonderful product! A
very, very satisfied customer."
"The E-Series HD590
cable sounds significantly better than the stock cable.....it may
take a few weeks before all the burning in is done for me to tell
you about the cable’s sonic qualities."
the E-Series for my Sennheiser HD590's and I love them!"
"...and I took a shot and never
thought I would say it but your E-Series HD600/580 headphone cable is
awesome!....I still can't believe what your cable has done to
improve the sound of my HD600's...... "
"Imagine a 55 year old whose been around the hi-fi wars for twenty
five years giddily wringing his hands, grinning demonically...and
that's with your E-Series fresh out of the box! Like a nice NAD
system to...oh, say, Conrad Johnson! What a match! The Senn
600's now show their speed with more of EVERYTHING related to
music. Okay, time to work the head amp and the front
end knowing every advance will be realized. Plus, no sound room to
fiddle and diddle with...this headphone stuff is FUN! The thrill is
"I just received the adapter and
l listened to your cable yesterday . Big difference from stock cable
more transparence details and really 3d sound imaging . It's sound
very good and I'm not using a headphone amplifier but a good
preamplifier output. "
"The E-Series in short, it's
superb - the best I've heard with my headphones! Break-in was
clearly an issue; the E-Series sounded closed in at first, but
expansively opened up after proper break-in. Truly a marvelous
product. Thanks again for a great product! The combination of
SACD, triode tubes, and headphones clearly produces the best sound
in my house."
picked up the cable at the Post Office... . After work I installed
it per your excellent product documentation. Removing
stock cable connectors was indeed challenging, which makes me all
the more appreciate of your installation instructions indicating
same. To be forewarned is to be forearmed!
a great cable...this headphone rig with the E-Series cable has more
detail. It is not forward. Bass is strong, has good
body and good attack. This cable does everything right, and it's
very well built. This is not a recommended accessory for the
HD600, it is a demanded necessity! Bravo Stefan AudioArt."
"Hello. I previously ordered your
E-Series cables for my HD600 and love them. I've buried the stock
cables somewhere in the back of my closet and hopefully will never
find them again!"
"I got the cables. They look great
and sound simply awesome......."
and Thanks for a great product. I've had this cable working with my
Senn.575's for approx. 15-20 hours now and the sound just keeps on
getting better. Detail, depth and musicality is wonderful! Doing an
A/B/A comparison with the stock cable after a few hours of break in
with the Vision 1 was revealing. The Vision was less cloudy, the music
more open with each instrument standing alone. I look forward to much
pleasurable enjoyment in the future and thanks again. Good luck."
"Your HD600 cable is nothing
short of amazing - what an improvement in every way you evaluate sound.
A must have upgrade over the cable supplied in the box!"
"Well, the 'Stefan
AudioArt' replacement cable: I just plugged into the
headphones-amplifier and the first thing I perceived was ... A BETTER
DEFINED BASS. Yes. The 'mids' and 'highs' still are, as usual in the
HD590, very detailed and well represented, but the bass ... God, what a
bass! As promise by James Serdechny, his cable leads to 'natural
high frequencies, clear midrange and extended low frequencies.' True.
But for us, the most important thing was the 'bass', and there it is.
The cable has improved also my perception of the changes produced by Jan
cable you sent is great, just as advertised. Thanks very much."
E-Series cable came last week. To say I am pleased would be an
understatement--marked improvement in detail, soundstage, etc...."
"A few months ago I bought an
E-Series cable for my HD590s. A great purchase.
Wonderful addition to sound quality."
