These accusations of delusion, snake oil, and such are derogatory in the sense that you are claiming others are so gullible or easily mislead, when you don't actually know that to be true in any specific instance.
There is an easy solution - measure it. Measuring the sound output of equipment is very easy. All you need is a sensible microphone and some software. These kind of frequency analysis curves are standard, like done here: http://www.learningaboutelectronics.com/...io-signals
If you can hear a difference in the sound quality, it must be visible in the frequency spectrum. There is no voodoo behind this, just simple physics on how sound is transferred in air to your ear. Yet I have never seen anyone who sells these expensive parts (cables, dedicated RAM modules, audiophile wifi repeater, network switches, ....) to come up with any prove, while on the oposite side (check the audiosciencereview forum) there are tons of tests where they debunk these claims.
Some of the many ones:

My favorite of all: https://www.youtube.com/watch?v=w31DQniFSEs - a blind test between a HQ digital cable and a cheap one which you can do on your own. I can only recommend to listen, compare the sound quality between the cables and then in the end look at the technical details of both of them.
But I must admit, something like this here looks/reads much better: https://hifireference.com/hifi-reviews/a...omparison/ - the only backdraw is: only "blabla" with someone describing his feelings, but no measurements at all.
And yes, I believe I am kind when I warn people of blindly following whatever they find on the net, because it can and will cost them a tremendous amount of money which can be invested somewhere else, like in better loudspeakers or a different amp.
