Audio reports have NOTHING to do with excessive IMD. IMD is by
definition mostly OUT of signal band products, so the other guy's
receiver (when tuned to YOUR frequency) does not hear them.

Then that is almost CERTAINLY due to your exciter and NOT the
amplifier. Amplifiers never enhance audio quality, they only degrade
it. By the time they degrade it enough for anyone to notice distortion
on your operating frequency, you would be trashing the whole band.
Not to be sarcastic to you, but the notion amps cause " good
audio" or "bad audio" seems to come straight from CB band operators.
At least that was where I heard it mentioned first. They think
class C PA's make the best audio.
Unfortunately, this totally untrue idea seems to have worked itself
into the Ham area now.
"Hows my audio?"
"It sound's great."
"OK thanks, then I must not be splattering."
I heard that just a few months ago, and the good audio station was
about 30 kHz wide!
