thanks for the info. Yeah, I knew that bitperfect is not connected with jitter, but I've never fully understood the asynch USB method of reducing jitter. Your explanation helps. -- garym ------------------------------------------------------------------------ garym's Profile: http://forums.slimdevices.com/member.php?userid=17325 View this thread: http://forums.slimdevices.com/showthread.php?t=84903 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
