Into a 10 K pass amp would be Foolish.

""""Regarding your specific match up-I can’t provide technical reasoning other than the PL probably won’t be a "wrong" choice,only your subjective approval.""""
 
I would strongly suggest you stay out of the advice Giving department for a while.
  Glad your having fun mindlessly recommending though.

Accepted audio sonics often defy  electronics 101 rules in one way or another.

You plumb your components with specific cable and other seemingly ridiculous items don't you?

So just reply directly to the OP with your all knowing audio wisdom and save the condescending remarks for somewhere else-grow up.

Ive not heard the Calypso but have auditioned the other 2 in my system. If your a rocker then the single tube CJ would be my pick given only those 2 choices.   

A general guideline when pairing a tube preamp with a SS power amp is that the amp's input impedance needs to be at least 10x of the preamp's output impedance. To be safer with the match, use 20x because at specific frequencies, the preamp's output impedance may be even higher than it's nominal value.

Pass Labs xa30.5 input impedance - 15k ohms unbalanced

Primaluna Dialogue 3 - 2500 ohms - Obviously, this preamp should be avoided.

Aesthetix Calypso - 1k ohms - Should be a match, but to be absolutely sure verify that it doesn't rise greatly at any frequency.

CJ Et3 - 100 ohms - Excellent match

Excellent advice.
