to make progress (as was made with slew) the "golden ears" and the
"propeller head engineers" (thats me) have to work together to solve
these problems...

if you think you hear something, the name of the game is to identify
something measurable associated with what you (think you) hear so that
the engineers can go fix it.

Nah the "golden ears" will never believe you can ever measure what they
*think* they can hear, and for the rest of us amplifier tech has already
surpassed the human auditory system capabilities (unlike speaker tech).
Which is not to say a bad amp can't still be made (and are) by those who try
hard enough :-(
