Modern Crown equipment is just fine - what you may call
"commercial" amps are more commonly known as pro audio
amps.
I know of a number of audiophiles with Crown amps in
large-scale systems. Also, some audiophiles myself
included
use QSC amps. The big gotcha with pro audio power amps
involve the ones with forced-air cooling, the dreaded
cooling fans.

What about the class of operation? I understand the Crown
amp runs in
A/B+B, so does this impact the sound quality,

Nothing wrong with class AB operation.

Here's a demo of the sound quality of a Crown amp:

Can you hear any degradation when you compare music, before
and after passing through this amp?

or the amps ability to handle complex loads?

Class A operation actually decreases the reactive load
handling capability of an output device.
