I’d add "quality" amp first, then power (watts) comes second but still important. With 92 or 94db sensitivity speakers, I’ve heard 8-watt tube amps with big, quality, transformers make wonderful music. Excluding class-D, most of the really good class A/AB amps I’ve heard or tried for fun with the Motion series had high build quality and always weighty designs, in general terms always 40lbs (per mono amp) or above. The SS stereo amp i tested with these was 87lbs. Big iron. Opposite of these amps at 17lbs with boxes and transformers smaller than your fist. Again, general terms but keep an eye out for big quality iron.
See @hilde45 prior reviews on Motion 60xt speakers I think it was, I believe he tested with at least 60wpc tube amps and some other solid-state integrated amps 60-200wpc range. He was dealing with room conditions as I recall yet got a sense of how the different amps complimented the Motion 60. I’d always buy a quality 40-60wpc high quality tube amp with quality parts before a 100pwc amp with lower grade design and parts, fwiw. Opinions may vary on this. Demo at home is best if you can.
