I think there is some truth in what you say Yuri. Audio listening is entirely "subjective." Why is that? Because the ear is an organ that is the ultimate transmitter to the brain. As long as all potential listening experiences are mediated by such a subjective piece of material, one can never truly say that sensory experience is universal. But by the same token, no one else can tell someone else what they hear or do not hear. You can't take what is for you a good, reliable means for evaluating and assume it is more true than another. I'm sure that people do want to hear what they want to hear. So you are right on that score. But by the same token I think it's also very possible for people to hear what they don't want to hear. For example, they might wish that their expensive cable is better than another expensive cable in their system but decide otherwise. And also it might be the case that their cable is better than the other in a different system. So much of this already subjective and context-dependent that you can't make the kind of universal claims you are making here. All you can say is that there is some evidence on A/B comparisons where people couldn't make blind distinctions. This fact raises some question about the reliability of certain high end gear being superior to others. That's fine. What doesn't go is the idea that you can draw too many conclusions from this.
