I have a Duet and a high-quality external DAC going into my preamp. My kids use the SB Receiver volume control and are perfectly happy with it. However, I always turn the SB volume up to 100 and use my preamp.
A few times, I noticed the system isn't really sounding very good. Invariably, it ends up being because I forgot to turn the Squeezebox volume back up to 100, which very audibly corrected the problem immediately. I can't assign this to listener bias because I didn't have a clue that was the problem. It is certainly settled to me that the digital volume control on the SB receiver degrades sound quality. However, I believe it is outputting 16 bits, so it doesn't prove whether the digital volume control can be used with 20/24 bits. My DAC literature claims 24 bit resolution, so maybe it will work if I ever upgrade to a Touch. -- mps ------------------------------------------------------------------------ mps's Profile: http://forums.slimdevices.com/member.php?userid=36351 View this thread: http://forums.slimdevices.com/showthread.php?t=77725 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
