Look class! This is the sound someone makes when they can’t produce a reasoned rebuttal to an argument.
Sorry but all your "arguments" are sophism around a mantra...the mantra is Blind-test....Your idea of science is akin to a comic book fiction... and in this comic book superman is a scientific superpower debunking astrology and ground bare walking.... Is it not pitiful enough?
Ears are not replaceable by equations or arguments...
Psycho-acoustic use measures, very precise one, of all kinds, but none of them replace hearing experience or even explain it...Psycho-acoustic is precisely an exploration of hearing mysteries...One of the problem for example covered in a 800 hundred page book i own is : what is musical timbre...
Save for religious scientism mind, measure of electronic design is very far to explain what we hear through and audiob system or what we could hear with an improved an audio system modified by many embeddings controls......
Dont test your ears ,educate it....
No human ears is perfect for sure, no need to prove it at all, but all ears can be educated by our own strike of EXPERIMENTS...For our own pleasure....
This audiophile claims of mine is not a zealot mantra like your obsession with blind test but an invitation to be creative....
