It's no use turning down a

what?

Sorry, it wasn't very clear was it? What I meant to say is that "high"
power amps are usually designed and set up to produce their best results
an appreciable way up to their rated power output.

No, they aren't.

They won't perform at
their best at a very low percentage of that level.

Absolute garbage!

I *know* that many are
*supposed* to be class A at low levels, but they are generally not
designed as class A amps, and are not really running as such (the output
stage quiescent current is usually too low to allow correct class A
operation on a class AB amp).

Excuse me? A class AB amp *always* runs in class A up to some
predetermined level, which may be less than 1 watt or as many as 50
watts. I use an amplifier which runs in true class A up to 50 watts
into 8 ohms, and in class AB above that level, up to its rated maximum
of 400 watts into 1 ohm. It sounds just fine at very low levels.

Thus it is a mistake to judge low-power
audio systems by simply turning down the volume on existing "high" power
equipment & changing the speakers for more sensitive ones.

Depends on the amp......................
