The only thing worse for this hobby than a quote like this (and I don't blame the OP for being fed this can of lies)...
"They have all the detail, air, and speed I need. If anything, they might lack a bit of body... Not to the point of being thick or slow..."
... are the people who perpetuate that nonsense and let those individuals continue thinking those are all real things. They're not. Those things objectively don't exist. They're straight up lies put out by manufacturers. Pure lies. You would hear no difference, at all, between an expensive boutique cable and cheap, standard 12AWG OFC (or even 16AWG). Because there is no difference. In some cases, the "bells and whistles" manufacturers put onto their cables actually increase resistance.
