I can't say i hear _noise_ as such with the switcher. It just modifies the sound to be a lot less enjoyable. And a quick A/B is not the way to find out either. One can tolerate a lot of signal-embedded junk and even find it pleasant for a short while. The proof is in eating the pudding over a longer period. (Injecting noise can even make a system sound more vital and energetic, but this will soon wear you down.) -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=31758 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
