Evidently, he's one of those guys who believes in running the
compression up to the point where a mouse fart in the next room will
move the power meter, and average voice peaks disappear into an almost
carrier steady power which rarely drops below 75% of peak......

In that case, the amp will be drawing more power that a capacitor can
make up for.

Even though you don't know it, you are agreeing with me.
Take a listen to SSB voice on any amateur band or CB if
you like. The preferred SSB signal is one which enhances its
intelligibility. This is done with some sort of compression which
will be a point in between your example and no compression at
all.

Recovery time is reduced with compression, and simply put the $50
spent on a capacitor can be better spent.
