Not enough power what does it sound like?

Excellent analysis above; I have painful, expensive, agonizing experience over-driving amps that resulted in damaged tweeter voice coils

though my system doesn’t sound ‘loud’, I know it is as soon as I try to engage in normal conversation; it’s clean, it’s dynamic, it’s a joy to listen to, but I really don’t sense how loud the system is once I try to talk with some one

I could not bear the loudness if it didn’t produce a clean reproduction and that requires sufficient power, more is better - and safer
