I believe the specs on the OCXO clocking options with the G-03X and G-02 are very similar to each other so you'd be getting a good solution with the G-03X (one that I've spent years owning and enjoying with a P-03U/D-03 combo) however the 02 is Esoteric's latest assault on improvements in that circuit, the unit in general and the master clocking outputs in general from what I've read. I've recently done A/B testing of a P-02/D-02 both with and without my G-03X clock and found that the new clock in the D-02 in master clock (22.x) output mode gave equal or better sonic performance to playback versus the additional complexity of the 3rd box (G-03X) in the system so I've taken the G-03X out of the system and have the P-02 slaved to the D-02 clock with very good results. The G-02 is based on the same generation of clocking in the D-02 with everything optimized beyond that for a standalone unit so I surmise the G-02 will be one hell of a clock.
You did not say what you would be using the G-02 or G-03X to be a clock source for. So, if I were guessing, I'd say;
- if you were utilizing the clock with a P-03/D-03, go with at least the G-03X and if you could afford it, the new G-02 clock versus a used G-03X to get the latest and most stable clock (the G-03X will have some age to i)....
- same note on other Esoteric equipment that accepts a clock (other than P-02/D-02 or the 01 series...) and other manufacturers transports and DACs; go with the G-02 to get the latest clocking technology with little or no age on it. Reason I mention age is that all manufacturers should tell you (Esoteric does) that all OCXO clocks will 'drift' a bit over time and with repeated handling, moving, etc....these drifts are small assuming careful handling but they do happen from what I was told (I am no expert). Rubidium and Atomic have little or no drift and are much more expensive....
- If using P02/D02, I'd suggest utilizing the clock in the D-02 as it sounds great to me this way and the extra money MAY not be justified...
- if using the 02 or 01 systems and you definitely want an external clock, the only move is the new Rubidium clock from Esoteric (the 01) or the prior G-0Rb or G-0s RB-oscillator clocks...
This is detailed stuff...let me know if I've confused things or if you have specific questions beyond this and I'll do my best to answer......
