Why? Because the guy asked how much jitter it takes to be

that
question is unimportant or irrelevant? Do you?

It's going to take a lot (whatever the electro-physico
explanations). In
the
early days of CD, when there were only 1 box units available to
play
discs,
golden eared high enders were endorsing 2 boxes; drives and D/A
converters
to get superior sound. Isn't that where jitter entered the
picture? One
box
delivered better (jitter free) sound.

By basic principles ( lack of need for a clock recovery circuit )
the
potential
for a 1 box solution to be superior in respect of jitter is indeed
true.

Just depends how clean your system clock is.

OK, and my point was/is that the listener who wanted the best and
latest
equipment for listening to CD was told (by insiders having good and
trained
ears) to go out and replace their adequate single boxes with two
boxes with
added jitter. So therefore "jitter" in *practicality* was/is a red
herring,

But the jitter that resulted from going from one to two boxes then
necessitated a third box, plus very careful auditioning of the digital
cables (two, now!) connecting these all up. Instead of simply accepting
the low jitter inherent in decent one-box designs, this approach puts
greater control over the final product in the hands of the end user,
thus restoring to digital some of the appeal of analogue.

Thus does the high end progress.

Well, it might surprise you that some of us stayed with a superior one box
(the Phillips 880) based on sound alone until a complex system came along
that was affordable and bettered it in sound (the coax digital - DTI pro
dejitterer/noise-shapper - AES/EBU -Proceed PDP). This combo bested the
Phillips (whereas other highly rated and more expensive one-box units
didn't). To this day this non-state of the art combo delivers more
accurate, pleasing, and analog-like redbook sound than even my relatively
new Sony C222ES SACD machine, which in turn was better than the marantz 63SE
that drove the outboard de-jitterer/noise-shaper/DAC combo prior to its
arrival.
