Phil, I think you've misunderstood what Mr_Sukebe is saying. He is saying that he hears differences in output *from the same DAC* when using different SPDIF sources. So he's not comparing one DAC to another.
That said, I remain unconvinced that jitter is the cause of these differences. Too many people say that there are only two things that can possibly distinguish digital sources: the bits they deliver, and the jitter. Not so - there are two another possible sources of difference that I can think of: a). The EMI radiated by the devices which can affect the operation of other nearby analogue circuitry. b). Grounding topology which may allow noise to transfer between the ground planes of devices. On unbalanced devices, the ground plane becomes part of the signal (in that the actual signal is in fact the difference between the "signal" and ground). Therefore if there is any noise on the ground plane it gets interpreted as signal. (*Perfect* shunting of the ground plane to earth is of course impossible). -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=78441 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
