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?

unfortunately, I can't seem to find any graphs for impedance but I know they don't drop below 4 ohms. I think I will need to home demo a few amps and see how it goes.

I'm using an external active crossover.


thanks guys.

I think I need to stick to something with 100w minumum for the top end, therefore. Something audio research is probably a good idea I guess.
