"Yes the optimal sound has left then returned an hour or day later but I usually fiddle the cables long before that happens."
Its possible that if the amp is on but not playing music that it might return to a more normal state when played again. What would work against the amp can't handle the load theory is if the sound ever improves after the suckout occurs while the music is still playing and without changing anything, not after sitting idle for some period of time.
