Amp for Sonus Faber Cremona's

I have a Classe Cam-200 and would like to give tubes a try.I would like to read what people think of the Cam-200 and tring tubes with this speaker.In the $5000 used market price range.
TUBES sound wonderful with this speaker!I listened to the Cremona with Graaf, Lua "Alborada"and McIntosh, of course.
What type of music do you listen to? Describe your listening room? What is in the rest of your system? These will all impact the amp selection.
I have CAM-200 setup along with Conrad Johnson PV-10. The sound came out of Magnepan IIC came out from this system is very sweet and extended in comparing with solid state receiver (used as pre-amp). The high current brings out the dynamics from the Magnepan, however, the bass still on weak, and need to have subwoofers to make them to sound right. Similar when used with Paradigm Monitor 7 driven by Conrad Johnson PV-10.

I have some issue with my particular amp because of they recently too hot to touch.
