Tweeter/Mid minimum amp power rating for magnepan 20.1 in active setup?


I have a pair of mint 20.1s in light oak, and I'm currently running them active, using a DBX analogue balanced crossover.

I am currently using a class A Plinius power amp for the tweeter/mid drivers and a pair of 600w monoblocks for the bass drivers.

I'd like to replace the plinius with a pair of valve monoblocks, but I'm unsure what the minimum power rating should be? Ideally, I want to use 845 or 300B tubes, but it is tough finding anything above 40w.

Any thoughts?

It really depends on how loud you want to play. A beefy 60 wpc would work for me but you don't want to cut yourself short with big Maggies. I'm a 100% tube guy but maybe a solid state amp is best for 20.1s. Big beefy tube amps cost a lot of money and make a lot of heat. 
Duke has it right. I'm 50% with tube amps on Maggies, some work some don't. Magnepan has never demoed with tube amps, that might tell you something.
