Hi Stefan,
Bernd said it allready. If you once notice the result of a "better" clock with
lower phase noise, you dont want to miss it anymore. Even if there is a lot of
vodoo and pseudo-sciences in the audio sector - and audio-nuts can talk hours
about things no scientist ever heard about. But the improvement of phase noise
is not an imagination. We are not talking about making something just "work".
In worst case, phase noise can lead to bit errors. better/lower phase noise
clocks will produce a better musical flow, better dynamics, better
representation of details and details that were notbeeing noticed before. And
don't forget - the quality of the power supply is not entirely unimportant ;-)
kind regards
Norman

I'm curious, too, what kind of audio application requires this level of
phase noise performance, and why.
Cheers
