3 points. 1. I am talking about data on a hard-drive. The correct frequency is in the file header - just right click the Properties of an audio file if you don't believe me. The frequency only needs to get encoded in the s/pdif data stream if you choose to transmit the data via s/pdif. 2. If all the 10 clocks mentioned in then NAIM white paper are for, say, 44.1K, what clocks are used for 96, 192 etc? 3. If all the 10 clocks are for, say, 44.1 Khz then at least 9 of them will be the wrong frequency, albeit by a small amount. An "approximate match" as you call it can hardly be called hifi. If the DAC switches between them to keep the buffer from over or underflowing then that is low frequency jitter. -- JezA ------------------------------------------------------------------------ JezA's Profile: http://forums.slimdevices.com/member.php?userid=21219 View this thread: http://forums.slimdevices.com/showthread.php?t=74471 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
