To add, the subject area of measurement does not correlate to what people hear, as the measurements have no idea what the ear is hearing, or how it hears.
the two do not meet, in subtlety... but only in gross terms. Ie, we can say what gross numbers in measurements, large variance.. may ~tend~ to sound like.
Those who DO know what to look for are generally quite silent, for all the right reasons. That is is part and parcel of their built up lore in cable design.
Incredulity and pressure laid down in the direction of those who say such things, will not change that one whit.
In some cases, it is an inability to understand Godel’s incompleteness theorem(s) as applied to the cart and horse of the science of electricity - as applied to audio. https://plato.stanford.edu/entries/goedel-incompleteness/
ie, to find the fine detail aspects of what one is looking for requires a far more complete and expanded overview (Renaissance multidisciplinary aspects) than is applied by those who continue to exist in Einstein’s take on the logic of incompleteness theorem, when in the world of endeavor:
"Insanity: doing the same thing over and over again and expecting different results."
"The height of stupidity is most clearly demonstrated by the individual who ridicules something he knows nothing about."
Ie, arguing that the obviously 100’s of thousands and ~into the millions of audio oriented people~..(even the partners and family members of audio people hear it!) who say they hear these subtle differences..and saying that they don’t exist and are some sort of placebo effect.
Then forgetting that hearing is like that of intelligence, and has it’s own version of IQ differences, and some hear better than others by magnitudes. Seriously. Indisputable. Real as it gets.
When not even knowing that recent studies in quantum research in such areas have, for the most part... put the idea of the ’placebo effect’ as a reality, deeply into question. So even that escape route of taking the simpleton’s way out..and blaming it on placebo aspects.... is being dashed against the rocks until it’s innards fry in the sun.
So, that cables deal with all the things the Geoff says they do, is real. It is a real thing, that we hear. And some of us take the time to really work out what is what, on at least some level. It is an expanding science, it is not a finished one. So we argue about it. But please, please, come up with something new. This is tiring and it is just ..well..beneath all of us.
But, importantly, we are well past admitting this is all real. What each aspect is due to, in complexity and simplicity... is the multi-faceted question. Arguing it is all hogwash.... does indeed show a lack of skill and intellect in this area.
I’m not trying to be rude, just factual. But it is perfectly permissible to argue any fact of any kind, as all of reality is a theory, and no such thing as a fact exists.
It is the ~only thing we do actually know~: that there are no facts. One fact - that there are none. Quantum paradox reflected in philosophy. Eloquence and correctness in expression, at it’s finest and most sublime.
So you go out and ask any professor or head of any science department at the top universities and research outfits, and they’ll tell you this exact thing. They’ll be shocked to think ..that you.. might think that they think --that facts exist. Go ahead. Go do it. Ask a real physicist these questions, go ask the top ones in the world, on any continent.
It’s only people on forums and some trained engineers who think that facts exist. Human existence is 100% theory and 0% fact.
Humanity cannot advance or change if facts exist, we'd be dead in the water. Deader than rocks. We'd be locked into an advancing and ever growing dogma that overtakes all and literally kills everything.
Lesson: Don't argue dogma for the nth time. Come up with something new and end the circular augment.
