[time-nuts] from Sputnik to CD

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 
this topic?

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.
