So long as you are looking at a conventional design a good amplifier
specification to look at is weight. Yes, weight. The components that
produce power and dissipate it have to be larger and heavier in proportion
to the power produced. I refer mainly to the transformer, but also to the
power supply, heat sinks, and chassis.

Some are.

In fact, I took a look at some of the cheapest sets online, and the $90
AMW home theater system at Circuit City.com has its power rated from
20-20k Hz. Not surprisingly, it doesn't come close in its power ratings
to anything else, at 30Wx5, 15W for center. The next lowest power
rating (by price, anyway) is Sony, 70Wx6, rated at 1kHz. There's
probably a lot less difference between those two systems than Watts
suggest.
