<< VRDS Esoteric players use a similar technique and buffer so that the same CD pits are being read many times >>

That's the first I've heard of that. I don't believe it to be the case.

And the "read until right" thing is just a myth. It's only required when a computer drive is ripping the disc at some ultra-high speed like 24x or whatever. Any ordinary audio CD drive will get all of the bits perfectly also.

<< is it the case that the over-engineering and superior disc clamping is resulting in superior information retrieval from the disc >>

Well, if that were the case, I would assume that it would be something easily measured -- jitter, cleaner "eye" pattern, et cetera. So I don't think that's it.

<< or is it that there is physically less vibration affecting the rest of the analogue circuitry? >>

I also don't think that this is the case. In the first place, if you stop and think about it, solid-state circuitry shouldn't even be vulnerable to vibrations. (But we know that it is, because different "footers" will affect the sound of solid-state components!) And in the second place, I don't think that ordinary transports create all that much vibration in the first place -- certainly not a lot more than the VRDS. And if vibration were a problem, then SACD would sound bad since the disc rotates at roughly 10x the speed of a CD.

Like I said, nobody knows...
