OK, that is an eminently practical point of view, and one that I suspect is shared and practised by many here. In an ideal world, it would perfectly. My only problem is that I suspect the world to be far from ideal.
It isn't that I think that all cables over and above the basic needed to conduct the current/signal are wrong, bad, or a scam, or that I think that all cable companies are thieves. Far from it --- although I have no doubt that a few of them are.
It isn't just the poetry, either. There is plenty of poetry in the marketing and reviewing of a lot of hifi equipment. Sometimes one would think one had strayed into a wine tasting! No, that sort of overblown talk may not
suit me, but where it is intended honestly, I can live with it. But when I read something that, according to my
knowledge and experience (this is not to argue the point about whether I'm right or not), is a complete nonsense, then I wonder why I should buy from a company that talks nonsense. There are plenty of other companies out there.
I may be wrong, but I doubt very much if I would ever find myself in a situation where just one particular cable or interconnect from just one company was vital to my system. There will always be a choice.
So, I might, say, look to see if a company sells eg network cables, and if they do, what they say about them and how much they cost. I have a better, personal, idea of the worth, value and technology of a network patch cable than I do about, eg a coax digital interconnect. So, it is a measure, for me, of that company, and accordingly, I might well chuck out baby and water and seek another bathroom. If I find them selling "audio" SATA cables, I'll be chucking the baby out the window and running out the door!
Probably, as with many things in life, much of the trade is a vast grey area. Apart from that, there are two extremes, with people selling utterly ridiculous
(according to me) products with claims that are either outright lies or sincere madness. At the other extreme are the companies that sell straightforward interconnects and cables, with decent to-spec connectors, and cable which has been shown by that awful thing
measurement to do all that would ever be required of it and more.
Indeed, there are cable companies that make me
feel like buying cable --- even though I currently do not need any. Did I mention that I really like the idea of speaker cables with
ultrasonically welded terminations? We all have our weaknesses
