MOSFET output stage

Well this is probably an urban myth/load of ********, but years ago lots
of people were talking about power Mosfets exhibiting different
distortion characteristics than BJT's in the same way thermionic valves
distort with differening harmonics and sound nicer.
Fact or crapology?
** Audiophool crapology - repeated parrot fashion, ad nauseam.
The THD residual of even the simplest topology, lateral mosfet audio
amplifiers is vanishingly small.
Sub the threshold of audibility.

Not if you clip them like you might a valve amp for example. Would a Mosfet
amp clip more "nicely" than a BJT amp? I'm thinking driving bass speakers.
Is this what some of these "audiophools" or pehaps PA guys are getting at by
saying they sound better?
