I've been running mine with a Keces DA-131 DAC since Monday, and am quite happy with the sound quality. To my ears it sounds just as good as my Cambridge Audio CDP. Now I do think the remote is horrible, but I knew about it before buying it. I am using a 80gig Classic. As far as the jitter #'s and possibility of jitter that quite a few people are complaining about, would someone please explain what I should be hearing if jitter is indeed occuring, because the music sounds fine to me. Besides for the absurd price of the MSB piece, I would hope it had better specs than the Wadia piece. Hell for the price they are charging, I would guess you could build a better music server.
