If you are looking primarily for PC audio, I'd suggest going with something that has async USB that can handle hi-res files (24/96 or even better 24/192). Otherwise you could invest in a USB-SPDIF converter, such as the M2Tech HiFace. Musical Fidelity just came out with a USB-SPDIF converter around the same price as the HiFace, and there are more expensive options out there as well.
Under $1000, I don't know of DACs with asynch USB other than the HRT Streamer line. I have tried all of the current models, and liked each one a lot. They are limited to 24/96 though.
Under $1000 without async USB, the below DACs are getting great reviews:
Eastern Electric DAC (you can choose between tube and solid state output. Had this in my system, and thought it was great for the price).
Wyred4Sound DAC1 (had the very similar $1500 DAC 2 in my system and it was only barely edged out by the Weiss DAC2 I currently use).
Rega DAC
Musical Fidelity's new M1 DAC
Audio GD also has a devoted following as well. But not familiar with the different models available at the moment.
A number of these can be bought from online dealers who offer a 30 day or so trial period if you are not able to audition locally.
