Effectively “Yes” you are wrong, for 2 reasons:
1. It’s futile “trying to have a rational discussion” with people who are not rational and even more so with people who are not rational and don’t realise they’re not rational! Obviously that’s a great shame (and often difficult to “bite your tongue”) as there probably are lurkers or others who are rational and might benefit from your rational posts/points.
2. It’s effectively against Head-Fi rules anywhere on this site except this subforum. For example, you’ve mentioned blind and ABX testing, that is against Head-Fi rules/TOS anywhere except in this subforum, because that is the most rational/definitive listening test for audible differences and is therefore exactly what Head-Fi strives to avoid as otherwise it would loose a very considerable amount of it’s advertising and sponsor revenue! All it needs is one person to take any sort of offence, report you and your posts will be deleted (and you’ll probably also be banned from the thread).
There are various ways of confirming cable differences (or lack of them) and they’ve all been done countless times over the course of the nearly half a century since audiophile cables were first introduced. In all that time, the audiophile industry has managed to provide exactly zero reliable evidence of any audible differences between cables (with some relatively obvious caveats) and never actually provides any objective measurements of their cables performance, unlike every other audio component, which by itself is quite “telling”!
