USB DACs with 24/192 via USB

Updating this thread;

There's the M2Tech Hiface USB to SPDIF interface. It will get you perfect audio output from a computer USB port to your DAC.

The Empirical Audio products are all now being made compatible for output up to 24/192. The website hasn't been updated with this info, but the Empirical discussion group at audiocircle received an official announcement. Email Steve and I'm sure he will be glad to confirm himself.

I think you will be seeing this as a common feature on many new products with USB

Audio Research is coming out with one (DAC 8)

Well, not quite perfect Firedog55 (your comments about the Hiface). A number of devices I have tried sound a lot better than the Hiface, albeit for more money.
