"You get what you pay for" in high-end audio is more of a joke than a truism.
Do you really, honestly think that a $300,000 amplifier blows away a similarly specced’ $20,000 amplifier? Wrong.
Does a $5,000 cable sound better than a $500 cable? Nope.
There are differences in the sonic character of different products and it is equally wrong to think that all amps, cables, preamps, etc., all sound the same. They don’t. But in this hobby people are snookered by the completely phony adage that spending more gets you more.
Who would spend say, $300,000 on a turntable and not want to believe that it is flat out superior to a $30,000 turntable? Or that a $20,000 phono cartridge blows away a $2,500 cartridge?
It’s all confirmation bias. And in many cases, it’s just ego.
Think of most of this stupid-money pricing as you would about fine jewelry. It may look cool, but most of it is worth what the parts are worth and the rest is just bling. Unless it’s collectible, then the collectibles market for that type of stuff determines what it's worth. No better than or worse than.
Do you think that the most expense collectible vinyl records cost what they do because the music is better or the recording quality is better? Nah.
This hobby is so full of BS that is sometimes boggles the mind.
In the case of cables, the really expensive ones, their price has nothing to do with the parts cost or the R&D (lol) cost. The profit margins on these price-bloated items are truly, truly obscene. Why? Market positioning and marketing and YOUR bias.
Now don’t get me wrong, some products cost far more to build than others. Speakers for example. But even a $1000 speaker can sound as good as or better than a $5000 speaker.
It’s just the way this crazy hobby works. It is what it is, but more money equaling more sound quality, FOR SURE, ain’t what it is.
Where things get the craziest in in the aspirational gear-- priced to create an exclusive club of owners, and hopefully, made to last a lifetime and designed to be be (in the eyes of the beholder) beautiful-- like a Ferrari.
Stuff’s worth whatever people will pay for it, but it is not necessarily better because of it.
