Esoteric N-05XD clock recommendation

Hello all,

I'm very excited to be getting next week an Esoteric N-05XD. When I auditioned it it was connected to a Master clock which convinced me that having one really enhances the sound. The only issue is that the master clock that was used (Soulnote X3) is not available to buy in the US. So I've been trying to read up on other clocks I could add to the N-05XD. My budget is not unlimited, so I've narrowed it down to a few options:

- Esoteric G02/G02X or second hand Esoteric G01
- Mutec Ref10
- Cybershaft (not sure which one)

Out of all of these, which would you say is the best for the N-05XD? And if it's the Cybershaft, which model would be most suitable?

Or maybe there's another model in a similar price range I haven't considered?

Thanks!
