The CD and line level inputs should be identical electrically. (CD is a line level source).
In your setup, theoretically the best sound quality will be obtained with the squeezebox volume set to max. Once you reduce the volume by 6dB or so, you will start to lose dynamic range coming out of your DAC. However, your amp and speakers dynamic range will also reduce with reduced volume, which will mask this effect. Given "The amp actually has separate volume control for both left and right, so it's kind of a pain in the ass to volume-match correctly" I would adjust the amp volume once so that maximum squeezebox volume is equal to maximum normal listening volume, and then use the squeezebox to adjust volume on a day to day basis. If you plan to have a party or something, then you can re-adjust the volume on your amp for the occaision. -- bludragon ------------------------------------------------------------------------ bludragon's Profile: http://forums.slimdevices.com/member.php?userid=1530 View this thread: http://forums.slimdevices.com/showthread.php?t=18863 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
