Esoteric G-ORb Master Clocks in general


I have been reading about the effects of an external clock and it has me wondering. The goal of the clock is to get the Transport and DAC working together. This will reduce clock jitter. My question is wouldn't it be better to have the transport sync with the clock in the DAC instead?

PS. I am not saying the Esoteric units aren't any good or anything like that. I'm sure they are wonderful.

dCS contends that their external clock is superior to slaving the transport to the DAC clock as master for lowering jitter.

While one would expect a company which has a $10k external clock to contend such, others have told me the improvement (with dCS gear at least) is quite audible.

Antelope Audio has a temperature controlled crystal oscillator external clock for about $1400 which is much cheaper than Esoteric's or dCS' offerings. I've not read of anyone using it outside of studios, though.

I've read that clock stability and jitter reduction "processing" are more important than clock accuracy. The Rb oscillators, at least by literature, are both very stable and accurate. The jitter reduction schemes seem to be proprietary DSP-based animals and surely impossible to directly compare as entities separate from the rest of the unit (oscillator, etc).

Seems, like many other things audio, you pays yer money and let your ears judge.
The Antelope "Isochrone 10M" Rb clock outputs at 10MHz and is NOT a standalone external clock. One must synchronize/slave an external clock to it. The dCS Scarlatti and Antelope temperature controlled crystal oscillator external clocks can accept "Isochrone 10M" input. Perhaps the dCS Verona and the Esoteric "crystal" (don't know the model #)clocks can, but I don't know for certain. Obviously, Esoteric's top end Rb oscillator clock need not apply...
