I listen to both CD (wife's mandate)and a NAS based flac files. I placed EA Pace Car between both my traditional transport and SB3. Pace car connects to my Northstar 192 DAC via I2S connection. Pacecar definitely cleans up a CD or or music files from a server. I definitely notice more resolution as I can start to locate individual instruments in a large band or orchestra. I wouldn't say the sound stage got wider -- I would say I hear more depth as I can recognize more layers from front to back. I guess some people would call this holographic. Anyway, EA Pacecar does that for you. My SB3 is only modded to "communicate" to my Pacecar and is stock otherwise. I even have the stock wallwart. I just doesn't matter what comes out of the "transport" as long as all the bits are there. Pace car will reclock and feed your DAC with synchronized file.
How would you improve the sound of Squeezebox?
I just set up a NAS music server with Squeezebox Duet. The convenience of accessing all my music collection is really a great thing. Now the question is, how would you improve the sound of the Squeezebox digital output? I heard people say that SB's outputs digital signals with much jitter, so what DAC's(~$1000) would you use to reduce the jitter? i.e. what DAC's has the better ability to handle jitter? Any other ways that you can improve the SB's SQ?
