Thanks all. A few more things @soix ask about I should have included. For budget I'l like to keep <$5K, $6K would be tops. Main reason for new would be trial audition period. Buying used but new enough not to need parts replacement can save $ but I don't want go through reselling if I'm not satisfied. And my line stage has RCA outputs so prefer not to need adaptors for balanced amp inputs.
I'll repeat, I have reasons for a stereo amp so no mono blocs considered. Also I don't expect SS to sound just like tubes, but I'd like a bit of sonic warmth and fullness.
I expected some suggestions for Class D but I've never heard one and no local auditions available. So that would definitely need to be new with return option.
Janszen recommends the 100-250 power range at 8 ohms. I've found less than that reduces dynamics and aliveness.
