OK there are 3 major problems that audiophile people have that no audio engineer who records or mixes music concerning cables has and that is
#1- Of course a cheap cable is not going to sound very good there are many reasons why poor quality cables don't sound good from being to thin to oxidation to having crimped ends. Audiophiles who compare inadequate cables to well built cables are comparing apples and oranges.
#2- I started my sound career 40 years ago live mixing and editing radio shows, the other editors always listened at 2.5x speed it was hard for me to understand the dialogue at first but after my brain "burned in" I was able to edit at fast speed. That to say your brain is variable it compensates for everything in the sound world and when you pay 10k for your AC cable you will hear a difference, there are definitely many emotional reasons but zero technical reasons.
#3- The description of the way cables make a difference include words like warm, airy, tighter low end, and imaging. All these things can be measured and measured very easily and accurately with way more resolution than your ears so those descriptions are proven incorrect. If the description were less technical like "musical", "beautiful", or "pastoral" then you could say there is no measurement for that, and ok who can argue with that, but that is not the case in most of your descriptions in this group.
