I absolutely agree. The critical point is that all the dac needs to "know" is 1) the sample values 2) the sample rate. Once the dac has received the manchester code bit perfect (which it will unless there is jitter equal to 1/2 the interval between bits (think about it) which is several nanoseconds for 16 bit S/PDIF)) then 1 is taken care of. 2) is not a secret for 16/44.1 it is errrrr 44.1kHz. It doesn't matter what the transport "thinks" it is. All the dac needs is a measn of keep enough data in biffer and a good clock to time the dac conversion. -- adamdea ------------------------------------------------------------------------ adamdea's Profile: http://forums.slimdevices.com/member.php?userid=37603 View this thread: http://forums.slimdevices.com/showthread.php?t=92918 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
