I heard the Streamer + at CES and quite frankly this is an amazing USB solution. The sound was very good even in a system set up in a hotel room. I'm not a big fan of USB, but between this solution and the M2Tech Hiface things are looking up for affordable USB audio with these entry price points. That being said if I were to go with a Music Streamer product I would consider either the Pro version, or HRT's next product offering that will be released this Spring, which will still be under $1000. The Pro version offers better parts, and allows for 24/96. The chip is the Burr Brown PCM-1704, which is well regarded. You could do a lot worse with USB.
Now if you really want to hear what USB can do and still leverage your own DAC, then the Sonicweld Diverter is IMO an excellent solution. I was able to borrow one from the distributor at CES and take it home to hear in my system. Quite honestly, it did not make me miss my CEC transport. Add to this I did not do anything special but rip a few CDs to my MacBook and run the music through iTunes. A couple of people were listening with me and were equally amazed.
