@zuul now let's assume for a second that this is in fact true. That these cables make a difference.
That must mean by simple logic that the cables themselves change the sound, and that there are at least 3 different ways in which the sound could be changed.
Then by just a tiny bit of more logic, at most one of those cables would reliably tranfer the original signal?
Of course, when asked to use logic, the customers for these things simply claim that they don't know how it works, only that it does.
I always thought there was a great opportunity to make money if one had no sense of morals; sell ethernet cables for better sound or something like that. I think the modern version of this would be a special keyboard that makes your ai music better if you write the prompt with it?
I hate to ruin your charming optimism, but, yeah....
