I think this is true, so long as the DAC properly buffers the data (not as easy as you might think - remember, the two clocks will never run at the same speed, so the DAC clock must re-adjust its rate dynamically). The Lavry seems to do this the right way - they explain how in a white paper. That should make the DAC totally immune to input jitter. However I don't think this ia the case for most DACs. If you're worried about electrical connections, use Toslink. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=29360 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
