Er, perhaps. Mosfets don't have the same thermal characteristics as
BJT's, which are more prone to thermal runaway. So perhaps when you are
runing
Mosfets hard, there is some kind of compression thing going on which
sounds nicer than a BJT amp exploding after clipping a lot.

Competently designed BJT amps don't 'explode'. It's not difficult, but the
Chinese haven't quite mastered it yet.


The point is that when people prefer one amp over another it may not be easy
to tell technically what it is they prefer.

Flatter frequency reponse perhaps ?


If a Mosfet amp compresses the
bottom end slightly over a BJT, for example, this might in the long term be
a nicer sounding amp. Maybe absolutely nothing to do with crossover
distorion, linearity, feedback blah blah blah.

How would this 'compression' occur ?
