On the assumption
that it should not hurt, I install a clock in every worthy
CDP which I lampize. It sounds at lest as good as before installation
and I can sleep better. I don't believe that JITTER is a big issue in
sound quality, at least it is a whole magnitude smaller contributor
than these horrible output stages which my lampizator replaces entirely.
What I can say, is that the sound with a clock is more coherent, and
left/right information is recreated more precisely, and this in turns
leads to better hallucinations, illusion of recorded time and space,
better background accoustic recreation. Definitely all these aspects
are WANTED.

This is one Polish made clock which I tried and liked. (AUDIOAMP)
Another Polish clock from DS Audio. Not yet tried. The author tried to
conceal his trick of the trade by some ugly grey goo.
This is a very very nice clock from DeTom (Poland). I tried 2 and liked
them both.
The big thing about using the aftermarket clock is that the mother PCB
is free from the strong ultrasonic oscillations of the quarts which
contaminates all circuits and the ground too. With external clock in my
opinion more benefit is resulting from the fact, that the clock
associated noise stays on the clock PCB and the power supply should be
separate - usually a small transformer dedicated only to supplying the
clock - than is resulting from the better quartz accuracy . Both
factors combined do bring benefits without a doubt.
If you ask me what is the most audible effect - it is the improved
effect of teletransportation to the recorded event. We feel like
being there, the nuances of recording background are palapable. Our
brain is better fooled which is a pleasant and desired effect.
