It would have been nice if our group (with our impressive, collective
talent, logical, scientific and mathematic abilities) could have
brainstormed this topic with a positive outcome. Might we have hit on an
idea or principle that would further our (and the worlds?) understanding of
The question about the relationship between SPDIF (and AES/EBU) clock jitter
and audio DAC fidelity is of interest to those of us (who can hear these
differences). For example, might there be a second order effect (with a
high sensitivity coefficient) regarding the effect of timing jitter on the
overall process of ADC / DAC audio processing (as some, here, have
suggested)? ...Or other mathematical relationships yet to be defined or
But, unfortunately, when it comes to this topic, there are always a few
discussion killers. Who wants to risk their peer status by offering their
findings, or theories (after some have posted put-down links, generally
implying that those who can hear these differences are fools)?

You might like to take a read at this.
which is in a web site of mine. To find it quickly, I used Google, then
see a few places link to it - I've no idea what this page says - I
guess it might be Romanian with the .ro domain.
