Hi Chris.  Well, I was partly tongue-in-cheek and partly pure sarcasm.  I 
keep hearing people who mold, model, shape, control, compress, bore, port 
and relieve their audio sigs on various rigs.

Invariably, the audio I hear sounds molded, modeled, shaped, controlled, 
compressed, bored, ported and relieved.  IOW, anything but good and 
normal.  I fail to understand how you can get a Hi-Fi 0Hz to 30kHz audio 
signal packed into a 3kHz bandpass.

Not to disparage all of these EQ'ed signals because many do sound pretty 
good.  But a bunch are overdriven, wide, hollow and distorted beyond 
belief.  When one asks these kind folks to reduce their gain (or whatever), 
they often get indignant and tell you that they have spent hundreds of 
dollars to get the "perfectly" shaped audio signal and that it must be your 
receiver.

I have a 756ProII and have yet to change the audio in any way.  The reports 
I get have ALL been positive.  I use a Pryme Desk mike and it seems to 
behave nicely. I bust pile-ups with relative ease and apparently get along 
with hams as little as 2-3 kHz away.

In any event, ask someone who is familiar with your voice to help you make 
adjustments and try to find two sets of settings.  One for normal 
conversation and the other to assist in busting the pile-ups.  In both 
cases, try to consider sideband splatter.
