Hello Spiroh
I've driven a pair of M3Tis with a 5wpc Antique Sound Labs MG S1 15dt tube amplifier (in Single End Triode mode). With a Velodyne subwoofer, it was audio bliss.
The M80s are a more challenging load. I'd go with a Prima Luna or Mystere, or Jolida Single End Triode amp in the 20-50 wpc range. Depends on your budget of course.
You're in for a treat. Not all solid state amplifiers sound the same. Not all tube amps sound great. It is a world of audio color out there. JohnK lives in a grey world, where all solid state amps sound the same and all tube amps are junk unless they sound like solid state amps.
Enjoy the music. Trust your ears. Avoid audio dogma. Don't be intimidated by audio dogmatists.
