I have to agree that Will's mind will never be changed. Moreover, there's
really almost no point to Les's side of the argument (no matter how true it
may
be or that I agree with him!).

Steve, there is a point to what I have been saying all along. I listed it in a
previous post but will relist it.
1) When operating an amp within it's designed limits, they will sound the same.

2) There are far more important things to consider than an amps "SQ", which
have been listed several times.

Number 2 is the most important one imo, But you cannot understand or get that
without first understanding number 1.
That is why I gave the advice at the start that I did.

In order to prove that Les and Mark and the
others are right (which they are!) you'd need to conduct testing under
conditions that simply do not occur in the real world of car audio.

No need. The testing has already been done. And you are right those conditions
do not readily occur in a daily driver. But it is still important to understand
the results of those contolled tests and what they mean for you!
It is not an argument over right or wrong, it is can you look at the data that
is there and use it to your advantage. Then actually make intelligent desicions
based on facts and logic rather than audio myths. Your system, and likely bank
account, will be most happy. But, obviously howdy and will cannot, they will
continue to be suckered by marketing gimmicks and overlook the important
things. Oh well, thier loss.
