Yes.

and are absolutely not involved in audio stage coupling
functions where someone "may" have a very very small argument
regarding types of caps affecting the objective (not measureable)
sound quality.

Agreed.

Take Sofie's advice and just replace them and no one will know the
difference except you of course.... and you will continue to think
that the sound is not what it should be. This is a mental thing....
get a grip and get over it.

It's entirely possible that the new caps actually measure the originally required
80uF whilst the old ones may be as little as 20uF due to ageing (mainly drying
out).

That will affect how the amp's dynamics sound when they are replaced by ones of
the 'correct' value.

The OP could try say 47uF or 22uF in place of the 80uF to see how it sounds. This
will introduce a danger of the amp 'motorboating' though.
