You call that evidence? By voting?
You think that receiver doesn't have any headroom? It may, or it may not.
If you drive that 80 watt receiver beyond its design limit as a rule, not as an exception, you need a better speaker or a better amp.

....one reason could be the damping factor is usually higher in a slave amp...
Absolute nonsense. Damping fator beyond 10 is not much use. As best I know all SS amps have sufficiently low output impedance to have at least 10.
I have posted links on this before. DF is a bogus reason except when it comes to tubes. We are not discussing tubes here, are we.
on and off the voice-coil more quickly...
Nonsense. Please read and don't repeat the same sin, ever:

.but I feel the main reason is the reserve of current supply that is ONLY being sipped....at reference levels, you may get into a decent swigging from the transformer, which would depend on the AMOUNT of headroom, and the peaks and the lows are FULLY covered, "MORE QUICKLY", for more clarity by cleaner definiton, low end cleanness of oscillations, cleanness overall, and I'm beginning to think most of your family wears Army boots, and can't understand "IT MUST BE HEARD, AND IS DIFFICULT TO DESCRIBE!!"....
What do you think the caps are for in the power supply but headroom???
If you don't drive the amp into the headroom region, it has no effect on anything. If you drive it beyond the headroom capability, you will clip. If you do this on a regular, continuous basis, you need to change something, speakers or amp.

...ahem....Mtrycrafts, here it is in a nutshell....go listen to one of your favorite CD's at a store that carries YOUR speakers you currently have, and tell them you want to hear YOUR speakers, first being driven by a receiver, and then by a slave amp that has at least 200 per at 8, hopefully 500 per at 8....the same reference level both times, picked by you, listening to certain parts of your favorite CD, now there it is.....
I'd rather you do these listeing comparisons under strict level matched conditions and DBT protocol. Anythihng else is just plain unreliable perceptions.
.....I know, what I know, what I know, and I'm seventh in line....
Well, you cannot know more than you do know, unless you expand real knowledge base
