Electrical noise in audio systems is not really a "theory" except in educational usage. It is well understood for 100 years now and there are well researched and practiced methods to mitigate it.As I understand your POV, you heard something in your system's audio reproduction you didn't like. You had some basic knowledge of electrical noise, probably from audiophile articles. So you shot-gunned various fixes such as replacing switch mode power supplies, trying cables that are claimed to get rid of the problem. Black box products that are claimed to eliminate said noise.
And you then heard positive improvements, so in your mind the problem was clearly electrical noise.
However you have no direct evidence of that. Electrical noise is easily measured and quantified in several dimensions. Especially today. Yet you performed no such electrical measurements and compared data before and after your tweaks. You assumed it works because to you, the problem was minimized.
What you fail to acknowledge is the problem of human expectation bias. You went to some effort and expense to swap a switch mode power supply. You like any person expects positive results from your work and investment. So lacking knowledge of the science and physics at play, you hear what you expect to hear. Another known issue is audible memory. It takes at least 30 seconds or more to swap a power supply or interconnect. The mind cannot retain the level of detail you claim over that time period. This too is documented.
I am hardly immune either. As I have issues with many of these questionable audio tweak products, I would most likely not hear any improvement.
This is why all areas of science and engineering rely on machine measurements where there is no chance of personal bias. And it also makes it very easy to stand behind your results because if accurate, anyone else can duplicate them.
I don't see where anybody is telling you what YOU hear and don't hear. This issue is your steadfast rejection of well understood and practiced scientific knowledge and practice. Things you don't understand at the level required to make the hard fast claims you do. And you also offer no technical rebuttal to these facts either. That just further promoted by the childish "I'm right and you're wrong" debate. That makes one look like a fool so why put yourself in that position. Just acknowledge what you hear and it's quite OK to offer an opinion as to what is happening technically. But it's ridiculous to argue with people who truly understand and further practice the underlying technology.
