It does just fine. Not as good as a BUD/UDAC of course, but it's not a missmatch or anything near it.

Sounds just fine to me. But then I don't nitpick things to death in terms of soundstaging and bass and trebble etc.
I listen to all kinds of music and although I haven't used this combo a lot (because I work from home a lot lately), the amp drives the headphones fine with plenty of power and does not sound constrained or anything like that at all.

HD800's are very easy to drive. Decent sensitivity and very high impedance. For any amp with sufficient voltage swing, they are an easy load and should allow the amp to perform at its very best.

192kHz/24bit fails

I am having trouble getting 192kHz/24bit downloads to play through the DAC. 96/24 poses no problems though. I am using Foobar2000 with WASAPI S/PDIF output on Windows 7. Here are the sample files I used:

Well, I got some bad news from Headroom support about this:


I'm so sorry I didn't get back to you earlier today (computer issues).

If the manual says it takes 24/192kHz, then I'm sorry to say that is a misprint. Only our newest Ultra Desktop DAC can accept a 192kHz signal. All of our other DAC's (including your Portable Desktop) can take a maximum of a 24/96kHz signal, and this is only on optical and coax.

So I'm sorry for any confusion in the manual, that was missed on our part. If you have any other questions, please let me know.

I came across this and was curious. Did you ever happen to check what yours has? Is this possibly a prelude to an updated Desktop Portable or just something you guys played around with "in the shop"? From what I've read in other threads, the DAC in the Portable Desktop is a slight step below the ultra micro DAC. If I remember right, the desire to conserve power in a portable design was a key factor (understandable). So then, perhaps Tyll's franken version is a custom mod they they would not offer due to shortened battery life via the use of a max module...

BTW, I just came across this glowing review of the DTP in Positive Feedback's Feb 2009 issue:

That review made me very very suspicious

 

 

"You can order HeadRoom's products by phone. The number is: (800) 828.8184 . When you phone 'em up, tell em Max Dudious sent you. If you're looking for a dynamite sounding amplifier that doubles as a travel and desktop piece, I'm pretty sure you can't do any better than HeadRoom's Portable Desktop Amp. It is really pretty fine. Best In Class. Ciao Bambini, on Feb. 2nd, 2009, Groundhog's Day. Any excuse for a party.

Max Dudious: Party Animal!

Ciao, Bambini."

The HD800 sounds quite good on an iPod. So that hard to drive are they not.

Yes, the term is called 'shilling.' This doesn't seem suspicious to me at all though, just because the guy liked the amp doesn't mean that he's being paid for his services... Headroom is a very upstanding company and a service to the community, and I'm mildly offended that you would jump to the conclusion that they're using shady advertising practices.

Are you a shill also? (just kidding) I'm new in this territory of putting hifi on your head, so please excuse me

No big deal, dude. Headroom amps haven't really been FOTM, so whenever you see a review, it's usually a pretty good indicator of the quality of the unit. What you do have to watch out for are the new products (from any manufacturer), because those are going to garner glowing reviews that aren't necessarily very accurate.
