I can appreciate that some of the less expensive DAC's listed above are good buys. However unless you can reduce the jitter you probably won't be happy with the sound quality. Take a look at the Benchmark DAC1 USB. It will reduce the jitter and the USB version has their best OP amps. Should cost $900-$950 used here on Agon.
There may be others as well, but the jitter reduction is worth the investment.
