If that's the case, then I can't think of any SS that wouldn't work.
However, many tube preamps have relatively high output impedance specs that make them poor matches with anything below 20k, so while Jim says the Calypso will work with just about anything, I'm hesitant without knowing the actual output impedance specification.
There's a used BEL 1001 MK V in your price range listed now.
If you are driving speakers with substantial swings in their impedance curve, you're going to want a SS amp that doubles power as impedance is halved.
