Call Alan Yun of Silverline Audio and ask him for his advice. I did. He straight out told me for the music I listen to (rock and jazz mostly), anything less than 100wpc in a tube amp won't produce satisfactory results on the Sonata III loudspeakers, and Pass labs or Belles solid state amplification would yield the best results. My experimentation thus far confirms his advice, although there are a hundred tube amps I have not auditioned in my system, and one of them might really be magical.
Alan primarily voices and demos his speakers with a Pass Labs amplifier of significant wattage.
FWIW, my room is 20x16 and partially opens on to a 12x12 room on the back wall. My listening chair is 8 feet from the back wall, and 9 feet from the speakers. I listen nearfield.
