On both DACs, different quality digital sources sounded different, implying that neither was fully successful in eliminating jitter. -- Mr_Sukebe SB Touch, Meridian 568.2, Bel Canto Evo2i, Impulse Ta'us, Coherent system, audio-technica and Zanash cables, Stillpoints Mr_Sukebe's Profile: http://forums.slimdevices.com/member.php?userid=10609 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

Just because a DAC sounds different does not necessarily mean jitter is involved... every DAC has a slightly different filtering circuit after the DAC and a slightly different analogue output stage and so will have a signature sound of its own.

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

Sorry Mr Sukube. I think your item B is of great interest, plus contamination of the mains from RFI. I've been playing with my RFI sniffer. Some interesting results so far, but it's too early to form any definite conclusions. I'm in the processs of switching to shielded mains cables... (I already had them on half my equipment). One thing - the amount of RFI from the mains lead of my (LCD) TV in standby is worrying... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
