@decooney My pure Class A solid state 50w amp with mosfet opts (always on), sounds better than my other Class AB amps where the first 10w was supposed to be Class A.
Good point, pure Class A is another option. I am guessing that amps designed that way are simpler and on average probably deliver better sound. I considered it myself, but opted for a high current amp with 18 watts of Class A on the front end. Pretty sure I rarely cross that threshold these days.
