Have you measured that, or do you know a reference? Another interesting idea is the Lavry way of doing things, where the local crystal has an adjustable frequency, and there's something that monitors the state of the buffer and adjusts the clock speed as needed. Is that what you were talking about above (VCXO etc.)? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=37044 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
