@thespeakerdude When we speak at low levels our voices don't sound the same as when we speak louder as does a saxophone that plays softly doesn't sound like one playing loudly. When someone has automatic loudness DSP they are fooling themselves in more ways than one. As you said speakers and amps don't perform the same, the Fletcher Munsen curve is not the same, and the physics of the acoustic waveform are not the same in real life. I think part of audiophiles confusion is of course #1 marketing to rich people based on arrogance, but a close #2 is living in 2 worlds of music. If an audiophile wants to recreate an analog orchestra there are much different considerations than recreating a modern music group with computer based information.
My Spiro Steinway grand that plays by its self is the perfect example of high end audio it sounds nearly perfect. There is so much difference between high end audio systems and the real thing it's not even worth talking about. When we see live music it's usually run through a PA and take it from me there are huge compromises when it comes to fidelity in every PA system and operator. I believe the answer to this problem is to understand the differences in our goals.
