A notable statement by the person with whom you were debating was:
Are they aware that the S/PDIF interface has a defined jitter margin? If I am remembering correctly, it is +/- 20 nanoseconds for 1 Fs (44.1 kHz/48 kHz) transmission, which is what the vast majority send over S/PDIF interfaces.I would refer him to the following paper, co-authored by Professor Malcolm Hawksford, a distinguished British professor/academician/researcher/PhD/DSc/Fellow of the AES (Audio Engineering Society)/AES Silver Medal honoree "for major contributions to engineering research in the advancement of audio reproduction":
Is The AES EBU / SPDIF Digital Audio Interface Flawed?
An excerpt from its conclusion:
A simple model of jitter error audibility has shown that white jitter noise of up to 180 ps can be tolerated in a DAC, but that even lower levels of sinusoidal jitter may be audible. These limits place tough constraints upon digital interface design....180 ps is less than 1% of the 20 ns figure cited by the person you were debating. Also, Professor Hawksford’s paper was presented to the AES in 1992; presumably the increased resolution provided by many of today’s systems makes low level jitter even more of a concern than it may have been in 1992.
