Presumably the amp doesn't know what noise is, and will amplify whatever noise it is being fed just as happily as anything. -- bhaagensen ------------------------------------------------------------------------ bhaagensen's Profile: http://forums.slimdevices.com/member.php?userid=7418 View this thread: http://forums.slimdevices.com/showthread.php?t=45736 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
