Hi. I found out that the SilverStone EB01 is powered by the computer, and as that would degrade the audio, I wouldn't be interested in it. I was seriously thinking about the Sqeezebox, but I have Windows Media Center and think that buying it would be redundant as WMC offers a very good interface for playing songs from the songlist, etc., although I would still need an external dac. So far I have narrowed the field to the Scott Nixon USB tubedac, Audio Horizons TD 3.0, or Empirical Audio's USB offerings. I noticed that he is going to offer his own dac sometime later this year, I may wait for that. (Empirical Audio)
PROREC, Audio Horizons would be one dac to consider, their products have had very high praise. They will also construct a special interconnect for connecting from your computer to their dac, for a modest fee. Personally, I love the looks of their dac best, but, of course, the sound is 1st priority. Sandra
