Thanks for the responses so far. It appears that there are two very good USB DACs in my price range - the Benchmark DAC1 and the Bel Canto DAC3. The Wavelength Cosecant seems awesome but at $3500 is out of my range.
The Bel Canto is a bit over my budget but I would willingly stretch a bit if the difference in sonic performance between the two is significant. From what I have read, the power supply and the clock are both very high end which may justify the difference in price vs. the Benchmark. In either case, I plan to run the DAC into my Manley Shrimp tube preamp, so performance as a dual purpose DAC/preamp is not really my main concern. As an added benefit would the Bel Canto substantially boost the performance of my modded XA9000es (just using the Sony as the transport)?
