This has to do with the Hifiman Edition X v2 (I don't see a separate link for it): right now, it's for sale on Amazon for $1299.00 -- I have no idea why.  Here's the link...

I want to add my voice to the chorus of praise for Peter and Double Helix Cables. His cables sound stunningly good, both the cheaper and the more expensive models.  And they're simply gorgeous, flat out beautiful.  He has made several cables for me over the years, and has been terrific to work...

Dear Hifiman,   I love my new HM-901, a wonderful upgrade from my HM-801.  But one problem: I can't get my computer to recognize it when I plug it in via the included USB cable.  My computer recognizes all other USB devices I try, so it's not the computer.  Any suggestions?   Thanks,   Ken

sorry, wrong forum...

Dear Head-Direct,   My wonderful HM 801 seems to have a loose headphone out connector: when I walk with it in my pocket, the left channel cuts in and out, quite unpleasantly.  It seems fine when I use it without moving.  And the same thing happens no matter what headphones I use (my regular...

It's very easy to upsample files to 24-96; that way you don't lose anything, and the Hifiman has no problems with the files.

I also had that exact problem with my HE-500s -- one of the earpieces came off the headband; I got the screws back in (had to cut the fabric), but it did it again.  I sent it back to the retailer from whom I bought it (should I name names?) and they glued it together (??), and sent it back to...

I've heard that owners of HM-801s will be able to upgrade to the new HM-901 -- is this true?  How does one go about taking advantage of this offer?

I have both the AKG 702s and the Hifiman HE-500s. There is no question that the Hifiman headphones sound a lot better -- I love the AKGs, but the HE-500s are fantastic, much better bass, but better all around. NOW the only problem: I have had problems with my HE-500s: the ear pieces keep on...

I don't know; I'm using full size headphone, AKG 702s, and the blue board sounds great with it.  I've got some Westone 3s and other IEMs, but I just don't like them nearly as much as my AKGs...

I'm not sure, but I think that what's new is the blue board, which seems to be higher gain than the board that originally shipped with it.  I'm guessing that people thought that the original amp board didn't give enough gain for more demanding full size headphones, like some of Hifiman's.

Hello fellow HM-801 owners and lovers,   I am having real problems with cue sheets -- anyone have any solutions?  When I rip a CD to a single wav file with cue sheet (via EAC), and then convert it (and the cue sheet) to flac with Dbpoweramp, the HM 801 displays the cue sheet, but doesn't...

You can tell what firmware you have by going into "settings" and then "system info"; it'll be listed as "version."

fantastic!  Thanks for clarifying.

I assume you are upsampling the 88.2 files to 96, to play on the HifiMan? You aren't supposed to be able to play 88.2 files on it, and I've certainly  not been able to. I wrote to HDtracks about this, but have not received a reply; I certainly don't want to buy more stuff from them (the Glenn...

I'm using what appears to be the new standard board, rather than the blue board (which I'm guessing is the new GAME module -- why is it called that, by the way? -- for IEMs), but I used the blue board with my AKGs, with very good results at first.  I haven't tried either board with my Westone 3s...

Interesting!  Thanks for posting the pictures.  Neither of my boards is exactly like either of the two above.  The uninstalled amp card that came with the HM-801 is similar to the two "standard amp modules" you have above, except that the four round parts (capacitors?) are marked "CS 100 10V"...

I bought the Glenn Gould Zenph "re-peformance" recording of the Goldberg Variations in 24/96 from HDtracks, and when I play it on my HM-801 I hear what sounds like loud tape hiss, enough to make it unlistenable.  When I play the same files on my computer, or burn them to a DVD-A and play them...

Does anyone know where to get replacement screws for the GanQui amp bay on the HM-801?  Mine stripped the first time I tried to open the bay...

Dear HM 801 community,   My HM-801 arrived over the weekend, with two amp cards, one installed and another in a little plastic bag.  There is nothing I can see that indicates what the two cards are.  I'm pasting pictures here -- can anyone identify them for me?  Are all 801s shipping with...

Thanks for getting back to me!  But I'm trying to figure out what the two amp cards are that came with my new HM-801: one was installed in the player, the other came in a small plastic bag in the box.  Any ideas?

I'm just getting my HM-801 working (WOW, sounds terrific!), but I am not sure what the amp board that came with it marked  "headphone amp board v.2.0 for Ganqi bay" is all about.  Is this an alternative amp?  What are its characteristics or purposes?  Thanks for your help!

Ok, I've figured out the problem: I guess the Hifiman can't play 24/88 files, but it can play 24/96?  Is that correct?  Is 24/96 the only above-cd format it can play? One other question: a circuit board came with the Hifiman -- I assume this is another amplifier module?  If so, what are its...

I just received my new Hifiman HM-801, and I can't get it going.  I can't get any sound out of it.  First of all, where is the play button?  Is it the pause button on top, next to the headphone jack?  In any case, when I try to play a track, pushing that button and any of the others on it, all...

I'm driving my AKG K702s with my mustang p-51, and I certainly don't have any obvious problems. Maybe a defect?
