But this has nothing to do with the power produced by the amp. There is no doubt that they sound different. What you like, you like. The thing is that players have NO idea of how much power their amp is delivering to the speaker at any moment. Judging by perceived loudness is a poor indicator and, furthermore, preamp headroom, clipping characteristics and voicing all distort one's judgment and some amps run out of power at some frequencies, too. More watts=louder...ALL other things equal, which is rare when comparing separate rigs.
