"Yours is also your subjective view.
Of course it is. How could it not be?
"The flatter the frequency response, the less fatiguing the amp will be. It's just that simple. Whatever other attributes/detriments it has will be irrelevant."
I don't see how you can go from that to this.
"I'm well aware there's more than one kind of fatigue and the one in question is the painful kind."
Maybe you should pick one. Either you have one factor and everything else is irrelevant, or there's several factors that are relevant.
"I would say pain is the most relevant."
Maybe that's your view but another person may say different. Everyone makes their own choices. That said, I think most people would choose pain as the number one cause of listening fatigue, like you. And that's exactly why so many use EQ's and tone controls to roll off the top end. In doing so, they're moving frequency response away from flat on purpose to make the system more listenable.
