Benchmark has a good wiki with regard to outputting digital audio from a computer. On the following page they graph the distortion that iTunes creates when the volume is less than 100%:
http://extra.benchmarkmedia.com/wiki/index.php/ITunes_Distortion_Measurements I do not know how the SB3 handles digital volume adjustments and whether it suffers from the same problems as iTunes. If the external DAC that you mention has a volume control, it may alleviate the issue with iTunes. Hope this helps, Will -- musiklov3r ------------------------------------------------------------------------ musiklov3r's Profile: http://forums.slimdevices.com/member.php?userid=13166 View this thread: http://forums.slimdevices.com/showthread.php?t=38372 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
