On the one hand a watt is a watt. There is no way around it.
On the other hand, driving a tube amp into clipping is by far a less unpleasant experience as is the case with solid state amps, where, when they reach their limits, the sound breaks up, gets brittle and harsh. Not so, with well designed tube amps.They still sound musical, when the powermeter - should they have such a thing - are already well in the red.
ah and Vic, white bread is fattening, as is mayonnaise. You should try Pumpernickel!
Oops, I just saw that Elizabeth pointed out the same explanation, no Vic, not your sandwich, the amp thing... Should I erase my post? Nope, as the poet says: "Great minds think alike" (-;
