I agree avoiding S/PDIF altogether is a better approach. Benchmark also has plots illustrating the lack of any jitter sidebands, for a 10kHz sin wave with 5kHz jitter added. There are many other measurements there as well. There is no sign of any sensitivity to input jitter at all as far as I can see. http://www.benchmarkmedia.com/dac1/ -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38637 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
