I tried my M80s with a tube amp from a local dealer who came over to demo a few years ago and they sounded great. I love the sound of detailed speakers combined with a tube amp for acoustical music or most music with a lot of ambience. A tube amp alone wouldn’t IMO cut it for movies but for the music I demoed (Bliss - Quiet letters, Rodrigo y Gabriela, Buddhabar - Chill out in Paris) it rocked. I wish I had the M22s at the time since I feel they actually do a little better in the midrange and the highs than the M80s and would even have sounded better.
