You did not discuss about my point on how the sound travels through our ears canals, to the cochlea and finally to the brain which analyzes it - which we define as music or sound. Now if you could explain that process and how it is similar in all human beings - we all will stand to gain a lot. Please go ahead with your explanation - I am all ears.
I didn't address it, because, while a fine question, it was a red herring in regard to criticisms of ASR.
You don't have to know, for instance, exactly how every INDIVIDUAL hears everything to know, through experiment, general truths about what humans can hear! Just like we know that while sight varies among humans, no one is seeing X-rays!
So when Amir is for instance appealing to measurements to say that the signal difference between component A or B will be inaudible, he's typically basing this on what is known about the human hearing range in terms of db thresholds, dynamics, masking effects, etc. Could any of his diagnosis be wrong? Sure it's possible. But given Amir is familiar with the relevant research (and can cite it), you better bring something more than "No It's Not" or "Science Hasn't Explained Everything" or "But I Can Hear It, I Know I Can!" Appeal to the unknown is not an argument.
Further, Amir will also refer to the tons of research done by, and cited by, professionals like Floyde Toole, Sean Olive and others, which arrived at very strong predictive theories for what people will perceive as "better" or "worse" sounding, once confounding variables like sighted bias were removed. So the fact people don't hear everything exactly alike does not entail strong trends or patterns aren't there to be found.
