Class A Solid State Sound

I guess so much relates to implementation.
Both Accuphase and Luxman amplifiers enjoy excellent reputations. Accuphase employs Mosfets and toroidal transformers, while their Japanese competitor, Luxman, employs Bipolar transistors and EI transformers.  Interesting indeed!

What you will get running a Class A Pass amp into a 2 ohm load will be a very hot amp that will probably shut itself down or burn a hole through your floor. Into 4 ohms and up Pass class A amps will switch to AB at their rated power and continue on probably doubling that. God knows what the Xs 300 will do. IMHO there are very few speakers with impedance that drops below 2 ohms worth listening too. The amount of power any amp will put out is determined primarily by the size of the power supply. Whether or not the amp can safely transfer that power to the speakers depends on the capacity of the output stage and the size of the heat sinks. Power is power as far as I am concerned. I do not care about the type of output device used. It is all about topology and durability. I expect an amp like the $90,000 Xs 300 to run for a life time. If it can't I am not interested.

MOSFETs obviously drive plenty of current into very low ohm loads.

Don't try to twist it again in other direction to save face.

The argument here has always been, what can drive "more current" into "low impedance loads"? Mosfet or BJT output stage, for the same given amount of complementary pairs.

 And the answer once again is BJT commonly known as Bi-Polar.
Give up your making yourself look foolish.
