If by 'immune' you mean that the bits are correctly interpreted, ie the received code is 'bit-perfect', then I agree, but I assumed that the jitter affects the clock recovery more than the values of the bits, since the clock is based on the timing of the transitions between bits. Of course, I understand that most DACs filter the recovered clock at the very least, and the better ones will buffer the input and play it out using an independent clock, so I can't see how jitter can affect the sound of such a DAC - bit-perfect reception and a decoupled clock surely 'solve' the source jitter issue. -- chill ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 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
