Since hearing is purley subjective, what's good for the goose many not be good for the gander so its best not generalize too much about this. That being said, I prefer a flat as possible response from the speaker (ignoring room effects) even if it makes some recordings sound bad. Why? I like to hear differences in the abilities of the recording/mastering engineers to see if they did their homework. I want the speakers to play the truth rather than smear the sound to make it more palatable. Thats what I look for. Your mileage may differ.

It is an observation of how we hear at lower levels - whether that is a live event or from our music systems.
Not lower levels only but across the spectrum. Human hearing is most sensitive in the midrange but is less sensitive on either side of midrange.
I looked at your F-M Wiki link, and thought it would useful to include a more detailed original version. This is from Knudson and Harris's "Acoustical Designing in Architecture", published by John Wiley & Sons, 1950. I highly recommend it.
Did you note the most important point about Figure 2.5?? This famous curve is only valid for PURE TONES. So, real music might look completely different than these famous curves but god only knows at this point what that might look like.

That's the way humans have always perceived sound!
That doesn't answer the question about an ideal room curve.
Nothing more
There's no need to compensate with how humans hear. What varies in our innate perception has to do with level .
Perhaps you noticed the steeper curves as level falls.
Did I say there was a need to compensate how humans hear?
Perhaps I did notice...Your point?
in observing that variations in the F-L curves are due to level .
"It is an observation of how we hear at lower levels - whether that is a live event or from our music systems. "
My bad...lower levels, not lower frequencies.

... Yamaha receiver makes that possible?
As long as your not driving the unit into clipping, then the Yammmy delivers it in spades without coloration. I find it both ignorant and tiring that audiophools think that an AVR cannot reproduce the soundtrack faithfully.
Clearly you are not up to date on the latest research into the impact of electronics distortion on sound quality...say from the mid 20th century onwards!!
Read some of the work by CHeever, Geddes and Crowhurst (from the 1950s and 60s no less). Also note that the problem with amplifier distortion giving a "sound" of its own has been known for a long time and has been the subject of research on and off for a long time now. D.E.L. Shorter proposed that it was the square of the amplitude of the harmonic and even that was found not to be extreme enough such is the non-linearity of perception.
I am sure that the Yammy does NOT produce color free sound at any level. Most of it will be insidious but some things like lifelike dynamics will be obviously curtailed...its just an outgrowth of the design philosophy they use in making their SS amps.
A Yamaha receiver isn't expensive enough to produce high quality sound. You have to spend enough to get above the riff-raff, preferably with tubes (ANY tubes). THEN you're talkin' good sound, and for Pete's sake, DO NOT EVER use a tone control.
Hang on...
I think my tongue darn near came right through my cheek. Gotta go.

too funny!

So 3db, evidently I'm receiving your replies telepathically and thinking they're my own. Man, wish I coulda done that in high school. Well, not YOUR thoughts specifically, but you get it. Dave
