What's the best USB audio interface?

I want to set up a dedicated music server on an old book-sized PC, digital out to an outboard DAC (a cal Gamma, but it could just as well later be another DAC) and then onwards through a headphone amp to cans.

So the PC will serve as the digital source or occasionally as a CD transport. There won't be any recording/input needs - and USB will be the way to go to bypass the onboard sound card (no free PCI slots anyways).

In searching for a suitable USB audio interface for this purpose, I've run across references to M-Audio/Midiman (sonica and others), Roland/Edirol UA 30 (or 3(D)), Xitel, Ego-Sys, Audiotrak - many more... the market seems to be moving fast ... I'm lost in the thickets.

I'm not looking for a one-off solution, consensus of any sort, nor do I expect to get great sound w/o a proper transport, better DAC etc. I'd be grateful if any a-goners could share their relevant experience (success? trials & tribulations?).

Thanks,
agonanon

We use and sell the Ego-Sys. I can verify that it is a very very good product.

The M-Audio sonica seems like a good choice. It's just like the Edirol, apparently, in that it has one coax and one toslink output. M-Audio makes good stuff, but I haven't used the sonica before. Considering the source material, I'd go for whicherver one is most affordable.

Apogee Digital just released the Mini-DAC, which offers USB audio input/output along with other various i/o options. More than likely overkill for what you want to do, but an option to consider

The Edirol UA-1A will do the job for you,
doing the D/A conversion as well.
But the UA-1D passes SPDiF/Toslink
to your DAC and I'll bet your DAC is
better than the one in the UA-1A.
Go for the UA-1D.

Interim Summary.

Thanks to all the a-goners who have breathed life into this
thread. Your input has been very helpful and is certainly greatly appreciated.

ESI U24 waveterminal (esi-pro.com, ESI=formerly Ego Systems or EgoSys)

Ballpark price points:
USD 0.1k - Sonica; UA-1D; Optoplay;
0.15k - UA 30, used; Stereo-Link 1200 ($169: 220-240V internat'l version);
0.25k - ESI U24 Waveterminal;
0.8k - Motu 828 (firewire 2xXLR or 1/8" to RCA);
1k+ - Apogee Mini-DAC (shipped Mar2003, price est. mini-me based);

Possible strategies:
- kiss (keep it simple,stupid): Optoplay; UA-1D; Sonica;
- added flexibility: UA 30; UA 3D;
- better build: ESI U24 waveterminal;
- consumer convenience: stereo-link;
- overkill: 828; mini-dac;

For the moment it seems that the k.i.s.s. strategy wd be most reasonable. Information/3rd party reviews/tests on the ESI/Egosys/Audiotrak products is harder to locate (they've got good mentions elsewhere in the forums tho). There are some unresolved issues: e.g. compatibility with the OS. Ultimately, I'd like to get this setup running under some flavor/color of Unix -- Linux or a version of BSD -- with a low-key text-based GUI (vs. some color and graphics-intensive one in windows) controlling the whole thing. There is some learning curve. The contributions are encouraging.
