| If this is the case, I believe there is some sort of distortion(s) in the signal (chain) causing the perceived brightness, not the FR itself.....
I think the evidence (starting from B&K and the recently posted work from Harman, and what Anthem does which it says is from NRC research) is against this. It's the frequency response: Down With Flat!
Your ear & brain compensates and doesn't think that in-room flat response sounds right. And experiments show anechoic flat isn't flat in the room.
To reverse Duke Ellington: If it sounds bad, it *is* bad.
J. Gordon Holt, 1985:
Many times in past years I have been impressed by the incredible flatness of the measured high-end response of some speakers: almost like the proverbial straight edge out to 15kHz, and sometimes beyond. In every such case, I have been equally amazed at how positively awful those loudspeakers sounded—so tipped-up at the high end that could not enjoy listening to them. (They aroused a deep nostalgia for the days when preamps all had tone controls.)
Nor am I the first to have observed that an objectively flat high end sounds tipped up. Ever since acoustical engineers started using equalizers to "voice" recording studios and monitor systems, they have observed this marked disparity between what measures flat at the top and what sounds flat. They were all ultimately reduced to pulling down the whole high end and—Heaven forbid!— adjusting it by ear. No one seems to know why this is so, but the important thing right now is that it is.
