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,

I've used this very combination, and there is no impedance mismatch if run in balanced. I totally disagree with Ben954. The Calypso is not dark in any respect at all. If anything, it can be a bit brightly lit in the top end with this amp. The Pass 250.5 is hardly laid back in the high end either. It is a decent match, though I would not recommend this combinaton with metal tweeters, only soft domes.
I am really trying to get a feel for the sound of these pre-amps. I was just corresponding with some one who owns the Grange model and sellng because he says 'microphonics are driving him brain crazy"

This pre is for a second system for me, not my main but I want to be able to get the best out of it.

I am looking at the Sauvigon or Cabernet in line stage only.

Thoughts would be appreciated.
Thank you all for your input. It has been very helpful.
Dev, did you read the title of this post?
Rhythmac24218, I don't no how that happened. Must be the pre-amp shacks or something.

For some reason the beginning of my thread did not go through, it was all about the Calypso and then asking if anyone had compared to bla! bla! bla! the rest of my thread which is there.
