I believe that Esoteric was (or still is ) sourcing their master oscillators from Stanford Research Systems (SRS). I was chatting with one of the SRS reps at a scientific conference a few years back and he said they were selling their OXCO and Rb master oscillators to a high end company. At the time, Esoteric was the only company I was aware of selling an outboard Rb master clock.
FYI-the OXCO oscillators go for about $250 in qty. of 100.
The Rb oscillator go for about $1500. A full Rb frequency standard goes for about $2750.
SRS makes really great stuff. I've been using their lock-in amplifiers, counters, and pulse generators for 15 years. When the instruments are calibrated, I would stake my life and reputation on their stuff. I doubt the Vacuum State Clock is as good as the SRS units on raw performance of the clock in terms of stability. For audio who knows.
The Rb frequency standard is pretty nice for syncing the time bases of different instruments. Pretty useful when you are looking at timing errors on the order of 25 picoseconds.
BTW-If you have to resort to using an atomic clock for timing and jitter correction, you probably should rethink your whole approach to audio. The Rb oscillator is basically an atomic clock in case you are wondering.
