If your lights are dimming, you've wrecked your THD+N by feeding your amp AC for the period the power supply filtering caps are empty. (It's even worse than AC, transiently, because of the effect of trying to refill the caps while driving the amp).
Also, the tweeter killing effect is because of the harmonic effects of clipping, so if you're hitting the rail voltages with any topology you're going to have a bad time.

When you flip on a 2-4kW pro audio amp, you can hear the electromagnetic forces for about a second. If you have a UPS on the same circuit, it will likely trip. That is empty. During normal use, there is no such thing as empty.
