I had a Music Streamer+, currently own a uDAC, heard the entire new Music Streamer lineup at CES, and currently have a Music Streamer Pro that I can't use yet (still waiting for the dealer to ship me unbalanced mini-XLR adapters). I'm optimistic about the MS Pro based on what I heard at CES, but if I had to choose between the Music Streamer+ I had and the uDAC, based on memory, I think it would be very close and the uDAC might get the nod from me (which suggests that the uDAC should probably be taken over a standard Music Streamer). I thought the plus version I had was very musical, but lacked a little bit of transparency, lacked some extension both at the bottom and the top, and was missing real bass impact. In the uDAC, these flaws are not as glaring at all (especially on the bass side, which is excellent). It really is an astoundingly good DAC for the price. I'd say buy without remorse.
