Why do my ears ring with my new amplifier?

"I'm not interested in arguing with anybody. But just for argument's sake, how does it not make sense to you that a flat FR will be less fatiguing?"

Some people roll off the high frequencies either directly with some type of EQ or tone controls, or indirectly using system matching to deal with problem frequencies. Altering frequency response, even if its to flatten it, will make the system sound worse (to the person who set it up, not necessarily to everyone.).

"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."

There's so many other factors that can contribute to an amps listening fatigue, besides a flat response, a book could be written on the subject. Timbre, distortion, material components, power output, phase, feedback, are all qualities I don't see as being irrelevant. You can if you want to. That's you're subjective view on the matter. Not everyone would agree with you.

Yours is also your subjective view. I'm well aware there's more than one kind of fatigue and the one in question is the painful kind. I would say pain is the most relevant.

"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.

I think you're arguing with yourself. Carry on.

Sorry, but their you're posts. You just don't want to be wrong.

"And before you come back and start arguing with me, can you back that statement up with something real?"

If you had an answer to that statement, something tells me you would find the will to argue.
