Clio09, I have read through many of the related threads here, on AA, and on AudioCircle. It also comes in handy that I am very knowledgable already about generic PC based media servers, networking, ripping, codecs, and all the other stuff that comes into play on that side of the world.
Regrading your comments, though, were you listening to the SB through its analog audio outs, or as a digital server to a high end D/A? Also, were they SB1s or SB2/SB3s? From what I've read there's a big difference between the SB1 and the newer units.
