the alleged differneces between amps , following the restrictions established by mr clark, are irrelevant with respect to purchasing an amplifier.
if i am considering two amplifiers, a conrad johnson mv 125 adn some current solid state amp, i believe i will prefer one over the other all of the time.
in this case it is possible that the cj amp does not meet the criteria for a fair comparison.
it doesn't matter, because i would use the cj amp with a panel speaker and prefer it to any solid state amp anyone could provide.
my point is, in the real world of amplifiers, some tube amps will not sound the same as some solid state amps, for whatever reason.
