Best tube amp s for magnepan 3.6r


I have a pair of 3.6r's. I am driving them with rogue m-150 mono amps. I think I need more power, but would like to stay with tubes. The system is used entirely for vinyl and the preamp is a CAT SL-1.
Any recommendations?

...do i change speakers---maybe???? and keep the amps??? or do i move the amps and keep the speakers???
Wolcott Audio P-220m monoblocks. I've heard them in Audiogoner Slipknot1's system with his Magnepan 3.6r speakers and it's an outstanding combination.

Wolcott's or VTL450 or VTL750.
The thing about Magnepan's is they love as much power as you can throw at them.
