The problem many people do not or refuse to understand is that just because they hear a difference does not mean that there actually is one.Is this a repeating groove bump in a vinyl called mijostyn brain?
What you think you hear is subject to the way you are thinking and feeling at the time which is subject to a plethora of influences and how you feel about them.
Your accusation make sense for a SINGULAR hearing test about ONE tweak.....
How do you explain by being hallucinatory, or by placebo effect, 2 years of CONTINUOUS improvements, with trials and errors in experiments with acoustical devices, electrical grid devices and mechanical devices listend to by me and my family? Collective audio hallucination or real improvements? What occam razor may say if you are able to think?
Do you really think that man can deceive not only itself but others also through a set of experiments giving incremental weekly positive improvement after another culminating in a complete transformation of his audio system for 2 years ?
I dont give a damn about your lack of logical thinking and your unreasonnable use of the placebo excuse to justify your own passive attitude towards listening experiments and your faith in ready made costly consumerist solutions, BUT
i dont like your supposition about people abusing others....Especially when someone boast about a multi thousand equalizer toy/tool for the solution to acoustical problems......
This is not placebo this is ignorance....Even about what an equalizer can usefully really do or cannot do at all.....
