The Art Audio Jota is "only" 20 watts per channel, but it is a high current SET, and played my Merlin VSM-SEs just as loudly as the 50 watt Cary 805C's could. You'd be surprised how loud speakers 90dB efficient/8 ohm, or better, will play with 9 or 10 watts. I drove the Merlins with the fabulous Fi X3 300B SET, 9.5 watts per channel, as loudly as I'd ever want on almost all music I ever listen to. The only time it ran out of gas was on some very high dynamic range (and listening level) classical LPs of full orchestral range.
SET-Cary, Unison, Wavelength, Other ?
Looking to purchase a SET amp(s) with flexibility to drive most speakers to reasonable listening levels without limiting my future purchase of speakers to monitors or just a few brands. Hope find great midrange, tight bass and open top end. I estimate 30-50 watts per side is necessary. Any thoughts or suggestions in brand or models that fit this broad range ?
