The volume control markings (eg. "-5") are not a good basis for comparison. It would be nice if 0 meant something like "some kind of reference level output with a specified input" or "as loud as you should play without clipping" but different mfgs seem to do different things.

Yes this makes it hard to compare two amps. Regrettably I think that was the whole idea. A more powerful amp will play more loudly without clipping, compressing the signal, or otherwise changing the sound... and may give tighter bass as a result of lower output impedence... but if it ever was as simple as setting both amps to the same volume and comparing the outputs, it sure isn't that way today.

A big-ass amp is still a Good Thing.
