Double blinding cannot isolate the ears or the brain because without them you cannot hear! Science does say exactly what I'm saying, people hear with their brain. Yes you can predict what a signal is like however that does not define how people hear it. The Klipsch speakers are an example as are others that some people love and some people hate. All I hear with Klipsch speakers is howling treble and distorted vocals, yet close friends of 50 years continue to try to convince me they sound great, I obviously agree, they do, to them.
That's simply a matter of preference. Some find a special shade of blue gorgeous while others find it gaudy.
But you can still measure its exact color with a color meter and calibrate a video display to be accurate, or tint a
auto paint color to match a damaged panel.
Serious studies already exist, they demonstrate clearly how the human brain processes information, including sound, and how precise the brain is at doing so. There is a fundamental issue, the mind doesn't play tricks, the mind responds to established principles and criteria. These principles and criteria are part of being human.
The part you refuse to understand or acknowledge is that YES, we all live in our own little particular auditory reality and it is individual to each of us.
BUT, when YOU go to a live concert it sounds exactly like a live concert to YOU.
When I go to a live concert it sounds exactly like a live concert to ME
A speaker that reproduces a recording of that concert that is and
Measures Accurate will sound like that live concert to the BOTH of us.
OTOH
A speaker that has tonal or distortion issues when listened to
without that live concert reference just falls back to a personal preference that has ZERO relevance to our own particular auditory reality. YOU either like it or not.
I like red, you like blue but if we're not color blind we both see the same things.
