Yes, even BB is not jitter free. I shouldn't have used the word free, maybe nearly jitter free is the better way to express it. When jitter is below a certain threshold, it becomes inauditable to our ears. No, my friend hasn't got measurement to back it up. It was a theory. He was able to tell the sonic difference on his SB3 when streaming wired or wirelessly. When streamed wirelessly, the sound is brighter and more brittle. This was done with WinXP and Vista. I've asked him to redo his tests with Win7 and see what happen. So far, he reports that Win7 is a much better OS for streaming servers. Last night, I pulled out my Duet, connected the Toslink output to my BB and had a listen. I use Toslink because it offers electrical isolation. The sound is closer to TP, but not the same. The piano note/vocal finish is not as long lasting and is a bit more bright and brittle. Imaging is less precise. When I switched back to the TP, immediately, the sound is more engaging and relaxed. If all digital bits are the same, then why is TP sounding better than the Duet on Toslink? -- Kuro ------------------------------------------------------------------------ Kuro's Profile: http://forums.slimdevices.com/member.php?userid=16701 View this thread: http://forums.slimdevices.com/showthread.php?t=74721 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
