I've actually already been interested in purchasing the E12a Iem Edition headphone Amp. I hesitated because I have zero experience with amps along with that if I spend an extra $160. on a headphone amp wouldn't I might as well purchase a used Ak100 II. Just my 2 cents   If the upgrade...

  Correct me if I'm wrong but is this the IE800 paired with the Astell & Kern AK120 II? If so, what are your thoughts and/ or impressions on this pairing.   -How's the treble and bass response -Is the treble at any times "ear-piercing" with sharpness -Is the bass ever overpowering over the...

Sorry guys but all I can bring this time is my new Fiio X5.   I will be purchasing the Sennheiser IE800s or Audeze EL8s before summer   PS- I used to own the IE800s except that the driver was deffective, I sent it back and they didn't send me a replacement :( I guess I can use this...

I am a huge fan of HiFiMans products. I used to own the HM901 and I would absolutely love to perform beta testing for HiFiMan. I have a huge passion for music and this would be a dream come true if I can review HE1000 and give some feedback back to you guys. Thank you for reading this reply...

For the AK100 II, I've searched everywhere but I cant find it for anything cheaper than $899. Amazon fulfilment return policy is great, but still 900 BUCKS!!!   Do you know a verified seller, who would also allow me to return it within 30days- (please provide a link)

What the 128 GB Walkman Hi-Res Digital Music Player?   That things got a pretty beefy price tag, I don't know if I'll be able to cut it 

Thanks for the comment.   But does it at least sound decent without external amps and dacs (Mine will be hooked up to Sennheiser IE800s)

Might be getting my AK 100 II soon, or if I'm feeling cheap I'll get the Fiio X5.   Does anyone know without looking at the specs of the AK240 and AK100 II, is the sound difference really that major?   If I remember correctly someone brought there AK240 hooked up w/ a DAC and beefy power...

From my understanding FLAC 16bit/ 44khz file from HDtracks will inevitably sound the same when compared to a ripped CD track.   Also keep in mind that a good amount of HDtracks albums are up-sampled, (meaning that the bit rate and khz rate was raised artificialy with a result of zero...

PLEASE NOTE THAT I HAVE NOT LISTENED TO EITHER DEVICE AND THE FOLLOWING COMMENTS ARE MY CURRENT IMPRESSIONS FROM READING OTHER REVIEWS FROM HEAD-FI.ORG   Well it all depends on your priorities. If your priority is to have the best "warm" and amazing detail retrieval sounding portable player...

I recently purchased the Sennheiser IE800 IEMs and I was amazed at the sound. I knew at that very moment that this was it. My hunt is over for the best universal IEMs. A few weeks later I discovered that the drivers were defective so I returned them   Comparing to the Cardas EM5813, should I...

  Another hint that it is a fake is if you see seams on the IEM or maybe the seams are sloppy.   For differentiating colors it may be a bit more difficult due to the fact that you don't have side by side comparisons. Generic PC and laptop monitors can't accurately display colors unless of...

  Sorry about bringing this thread back to life, but you said that the ak100 II has more trade offs than the ak120...why is that?   I have heard from others that the ak120 and ak100 II sound very similar in sonic performance, but the ak120 has more trade offs due to the slower and outdated UI...

  I gave the IE800's about a 10 to 15 hour burn in playing at a mediocre to high volume.-(should have given it at least 48hours before final decision)  I really should have bumped it up a bit to speed up the process but I was just to worried about damaging the precious little 7mm dynamic...

I think I might just order mine from an amazon dealer with fulfillment by amazon to get the full 30day return policy, though getting a fresh batch directly from sennheiser is still tempting 

Was this the link? http://www.ebay.com/itm/SALE-BRAND-NEW-SENNHEISER-IE-800-IN-EAR-HEADPHONES-IE800-BLACK-ORIGINAL-EARPHON-/171631093116?pt=LH_DefaultDomain_0&hash=item27f602a57c OR THIS...

I just returned my pair of IE800s to  bestbuy due to the trebles peak just killing my ears...it was just sooo high pitched from some albums. If I want the latest batch should I order from amazon or sennheiser   -If ordered directly from sennheiser wouldnt their return policy be more difficult...

HiFiMan quickly solved my problem. Thanks a bunch HiFiMan   HiFiMans Response Via Email:     "Sorry for the trouble you have incurred. According to our technicians, there may be inappropriate operation in the upgrading process. Please try again           by  following the instuctions...

Last week I purchased the HiFiMan HM901 (used) from an authorized dealer through www.amazon.com I have been using a 256gb PNY SDXC card flawlessly from the HM901, with only 40gb used.   The Kernel Version is K2.9 and the UI Version is 1.082. Due to the old and sluggish UI, I decided to...

fengwei007   I know this is an extremely late reply back to your thread but off of your comments I purchased the HM901 instead of the AK100 II. (The AK 100 II is often said to sound similar to the AK 120) I would just like to thank you for your deep/ emotional comments of the experience from...

I originaly was hoping that it would sound decent enough for me to keep but I guess my expectations were too high for this little device, along with that "BURNING IN" an audio player...What was Ibasso thinking!

I'm extremely disappointed with the dx90, I'm going to return it back to amazon and purchase either the hm901 or ak100 II

I know this is a late reply...But what does the burn in cable do.... I just bought mine and I have no clue what it does

I will most likely purchase the HM901, due to the high ratings and positive feedback. Along with that I will purchase the IEM amp card-- http://www.moon-audio.com/hifiman-hm-901-iem-amp-card.html   SO EXCITED!!! I'll keep you guys updated.
