More powerful amplifiers also provide a psychoacoustic cause for speaker
damage. Undistorted music often sounds less loud than distorted music
with
equal power. Therefore, a listener is more likely to apply more power to
his
speakers with a more powerful amplifier. In the absence of clipping, the
music will not sound as loud as it will if it is clipped.

This is an excellent point, and one that I had overlooked in the context of
this discussion.
