Maybe I see it a little different,
Which is closer to the truth, an experience or an explanation of that experience?
For me the later is woefully inadequate.
It is like me telling you about my experience of listening to a performance, you may deduce, you may believe, or you may be able to associate some aspects of it with previous (different but similar) experiences of you own, you understand my explanation but what you fail to have is the full impact of that performance in my experience. To me, this is why I find it absurd to only consider what is true as something that one can measure. I do think it is wise and reasonable though to be skeptical. Would you trust you experience if you heard cable differences but they could not be explained with science?
Would you belive me if I told you that the middle signal on a traffic light is purple, even though everyone else sees it as amber and a spectrometer indicates it is amber?
We ARE discussing things that can be explained and proven by science without the flawed "human experience" being used for any data.
Imagine this: you're in a room full of people talking att he same volume. You distinclty hear your name uttered by someone across the room.
This does not mean they spoke louder, it means your brain filtered out what it NEEDED to hear (this is the human experience part).
Another example is the video of a man saying "fa, fa, fa" (or something similar). There are two soundtracks for the video, each with two different sounds, but you'd SWEAR each one belongs to the video as you're watching it, no matter what the facts are.
The human experience.
Now, apply it to cables. Under the placebo effect, people may hear differences between two cables/etc. that are actually identical because they EXPECT there to be differences (like the guy who knows his car runs better after he washes it), or may not hear legitimate differences because they don't believe they should.
The human experience.
People will listen to a piece of music and "place" the instruments in a point in space, even though the recording was done in multiple takes by individual performers in a sound studio.
The human experience.
Despite proof that you cannot influence the outcome of random events, people with clutch to their lucky rabbit foot when gambling, and blame their losses on not HAVING that rabbit foot.
The human experience.
Science can be used to eliminate the very strong potential error of the human experience, and in the case of audiology, science can do everything needed to prove whether two things are the same or different (no matter what the PERCEPTION of thos two things is.)
