Aesthetix Calypso compatible with Pass amps?

I currently own an Aesthetix Calypso preamp and was considering pairing it with Pass XA-100 monos, however the Pass has an input impedance of 22k. Does anyone out there have any experience regarding using the Calypso with Pass amplification, and are there any issues? I know the Aesthetix website says it requires 10k single ended, 20 k balanced for best results, however 22k is cutting it pretty close. I would appreciate any feedback.
Thank you,
Darrin

Just so I'm 100% clear...

the goal is to min the ratio (all things equal) - so 10:1 is preferred to say a 36:1 -- or am I mixed up? I'm looking at moving to the very same combo.

I posted previously and was told SF Line 2 would be a nice complement due to its relative low impedance - a nice match for the pass

and what is the result of a higher versus a lower ratio - many thanks

(I understand there is much more to it than this one ratio...)

Thank you very much John - I was told previously told to match as closely as you can.
