There's a LOT of snake oil - especially on the topic of cables ... a pal who want to become an agent selling for an esoteric French firm was asked to pay £40,000 up front for some fancy cables in his show room. Just a pair. At this point we chatted ... I was on the verge of buying a very expensive pair of drivers from that firm, for the project above. Both of us had been asked to pay by bank transfer... which rang alarm bells with me ... what if the company is about to go bust? We walked away.
Cables do make a difference- and it's down to how well the impedance and capacitance team up with the rest of the system ... there is very, very little correlation to cost.
My view is - if you like it it's good.
I like to watch some of the hi-fi channels on YouTube just to laugh at all the descriptors used but they usually fail to acknowledge that you can have two people listen to the same exact setup and they'll have vastly different listening experiences. For example, I prefer soft dome or horn tweeters as opposed to titanium dome or ribbon ones due to my individual hearing, typical style of music I listen to and home speaker placement/acoustics.
This is why I still haven't fully replaced my Klipsch Heresy II's in the living room even though she wants me to due to them being completely archaic-looking when it comes to build quality/style but I also use some modern Polk Monitor 70 S2's I got off Amazon 10+ years ago for a steal that do really great with newer digital recordings/PC audio. Although, in the case of those, I didn't get to audition them because I took the chance based on general knowledge/word of mouth, which is NOT recommended unless you know some things about you as a listener. I got to the point, ages ago, where I was buying a DVD player based on it's supposed CD audio output quality but those days are long gone. Those 70k+ setups out there are pure folly, IMHO. A fool and his money, etc. A $12k mono block is insanity.
