No, the problem is that you base a far-reaching claim on
so-called listening tests that were probably utter crap.
They appear to be utter crap because there is no
indication of proper level-matching, no indication of
any checks to see that the amps are proper
representatives of their make and model, and above all,
no indication of any bias controls.

Right so at the demo I had no way of knowing what the
gain of the amplifiers were and so we employed a sound
pressure meter and a 1kHz CD test tone. I'm sure the
sound levels were within a db or perhaps at worst 2db.

More than enough to explain just about any kind of differences that you
think you heard.

But having done all of this, what are you supposed to do?

Recognize noisy data for what it is - noisy data.

1) Not bother to listen to it because they're all the
same.

How clueless does someone have to be to rerun the same straw man argument in
quick sucession?

Obviously, you have no pride in yourself, nor any respect for your readers.

2) Decide which you like the sound of but buy based
on price/facilities

At least that would be support by the relevant reliable facts.

3) Buy the one *you* think sounds
best *even* if it doesn't really.

Nonsense. You should have started and stopped with alternative 2.


When you get this home are you going to congratulate your
self for the life of the amp on the bargain you got or
the wonderful facilities it has (that rarely if ever get
used) or listen to the thing playing music?

Do what you want - base your purchase decisons on obviously false data, if
that's what you want to do.
