Whether solid state or tube, what your willing to spend is important. Tube amplifiers can tend to be more costly, so hopefully you are not working on a shoestring budget. Give us a budget and we will see what people can recommend. And yes, quality tube amplifiers can power speakers like the M80's.

BTW I am enjoying some AT headphones through a vacuum tube amp right now.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
