scientific double blinded cable test


Can somebody point to a scientific double blinded cable test?

„People and their ears are redundant”. Half-joke in response to claims here that double blind method  cannot study human behavior. So eliminate humans.
But in fact, if you check for error rates of digital transmission in cables the observer’s opinions are irrelevant. The same you can do with „voltage transmission”. Of course pundits here will claim that there is no method to reliably study human hearing which is quantum phenomenally more sensitive than any measurements.
I’m not against scientific studies, and gaining broader knowledge. For me, they just don't have much relevance or usefulness when pursuing greater musical enjoyment from my personal system. I'd rather have recommendations from one or more people with similar tastes and goals to mine, whose ears I trust.

>>>>That can’t be right since human hearing ability varies all over the place. Also it’s patently false that sound is completely determined by how the ears transmit acoustic vibration to the brain. That’s one of those beliefs we assume we learned somewhere along the line that everyone agrees must be true. What else could it be, right? But that’s a subject for another thread, another time, partner. 🤠
