As to soundstages collapsing due to cables not being treated as if they were unicorns: I have friends and acquaintances who are audio reviewers. I regularly hear whatever gear they have in, from expensive amps, to all sorts of speakers, all of them hooked up to super high end cabling.
Every time I come home from listening at their place I play the same tracks on my own system and...somehow....with my 35 foot long generic cables running under floors and over a rug....I experience glorious soundstaging and imaging (and clarity) of at least the equal if not more to what I’ve heard there. I guess I’m just lucky. (It’s ok, I’ll do this for you: "that’s because you have ears of cloth, not carefully trained golden ears like the rest of us")
Speaker set up/room acoustics/listener position will in all likelihood influence imaging/soundstaging far more than raising the average cable off the floor.
