Ah, you ask so little....basically, IN GENERAL it's the fact that the
AVERAGE tube
amp circuit uses little or no feedback. So its clipping characteristic is
more rounded, allowing you to drive it harder without the sound becoming
unpleasantly distorted with lots of very high-order harmonics. Virtually all
solid-state amps use a LOT of negative feedback, giving them very unpleasent
sounding clipping effects. So, for a tube and transistor amp with very similar
ratings and similar power-supply capacity, the tube amp can just be pushed
harder without sounding bad.

So do I. It will be difficult to "prove". This is why I end up in arguments
with old-fart engineers, they keep demanding to see extensive peer-reviewed
documentation of things about tubes I tell them. Such does not exist,
because tubes are DEAD TECHNOLOGY, and why would anyone want to
study them?.....
