Can single ended 211 or 212 amplifiers drive magnepan 20.7?

Dear All

I have been reading up about maggies and am chasing after a huge immersive soundstage that the maggies provide, and would like to combine them with a sweet and musical sound that single ended tube amplifiers provide. 

I currently own the cary 805 ae mono blocks which uses a single ended 211 class A output of ~25watts, and am wondering if an amplifier like this or something much bigger like the 212 single ended tube amplifier with 40-50w of class A1 output can drive the magnepan 20.7s? 

Cant seem to find much info on the web, or people with any experience. Would definitely appreciate any advice or sharing of experiences here! :)

Thanks in advance!

Cheers,
