Nah. I'm just saying making a decent audio cable is relatively straightforward and well figured out compared to what's going on elsewhere in the world, where design spec can be extremely critical. The same methods to test and analyse and source products are the same.
Doesn't even have to measure perfect. If you can hear a difference, then why couldn't a difference be measured too? Lots of stuff has a "sound" because it's actually performing pretty poorly, but has a "sound". But if there are claims of a cable having better dynamics, lower distortion, more headroom, "a more scooped sound", then even a user can easily test that stuff.
I don't disagree with the rest of your post as such. People fall for marketing, and if enough bold claims and non-sensible pseudo scientific waffle is thrown in to the description, people will fall for it and believe it. And If it makes people happier, cool. But it's essentially predatory behaviour targeting those who don't know any better. There is no reason for these cables to cost so much money, aside from the fact that there are people out there who are willing to pay for it.
Why not just record something through it and show is the improvement then? You thinking you can hear a difference doesn't even mean you CAN hear a difference, let alone there being any kind of difference.
As I said, let's hear it then. I'm firmly in the camp that believes cables can cause a difference in sound. More often than not, it's bad cables that have a sound, and once you hit a certain point, it's very hard to reliably hear a difference.
