The quality of digital audio depends only on the quality of the converters. If you hear sound difference between cd-transports, there's a design fault in the dac.

Dan has a good paper on jitter and phase locked loops on his website.

I can't find the paper on jitter and phase locked loops on Mr.Lavry's website.

Look on the support page, "White Papers"->"On Jitter"

A perfect transport would have zero jitter on the output.
A perfect PLL would have 100% jitter rejection, a perfect PLL is not easy, which is why Lavry products have CrystalLock.
If you can hear a difference due to jitter on the output of the transport, then they are BOTH imperfect.

No, only the pll's in the converter needs to be good enough. Then all jitter is rejected.
|
And how does that contradict what I just said? For you to hear a difference caused by jitter requires that there be jitter in the first place, AND that your converter does not reject it completely.

We don't disagree.
But if you hear a difference between digital cables/transports, don't blame the cables/transports.
Thanks for showing me Mr. Lavry's paper on jitter.
As far as my knowledge goes it's truthfully.
It also agrees with my statement: If the dac is properly designed, all jitter is rejected.
So if a converter reacts to different cables, transports or needs an external jitter free master clock.
Throw it in the bin.P.s. Put the "Proper word clock implementation" thread back where it belongs.
