Is there any truth to this question?

If an amp is clipping, there is a good chance the sound quality is negatively affected well before any any clearly audible distortion is noticed. Better to have an amp that goes loud effortlessly to provide headroom before any clipping comes into play. One might be surprisec what is needed to do this for less efficient speakers. The difference can be subtle but very significant. With the exception of very efficient switching Class D amps, some weight and size is usually required.

Completely agree Mapman.

I am of the opinion that most audiophiles underestimate the amount of power they need.

30 watts of power might be adequate to reproduce music at average levels for a typical speaker /room, but musical peaks can require 10x average power.

Most audiophiles simply don't recognize when their amps are clipping. This is because the clipping usually only occurs on musical peaks where it is very transient, and does not occur at the average power level. Transient clipping is not recognized as clipping by most listeners because the average levels are relatively much longer than the peaks. Since the average levels aren't obviously distorted, the listeners think the amp is performing within its design parameters -- even when it is not...

I cannot think of any speaker that is so inefficient that one would be listening to it at an average output of 30 watts so that a 10 db peak would require 300 watts.

Have you ever made any attempt to measure your power needs objectively or are you guessing? Objectively, 30 watts is not enough power to avoid clipping on music peaks of over 100dB for typical room and speakers though listening levels are not just a function of amplifier power but room reinforcement, room resonances, and room sound absorption all have a significant influence on the power requirements too.

What compromise have you observed with well engineered high powered amplifiers?

In my experience audiophiles under-estimate their power needs.
