I think this whole "golden ears" thing is one of the things that has killed the mid-fi segment (let's say systems 1000-3000€). The existence of extreme audiophile cult is widely know to general public and when I mention anything about my audio equipment I often get asked if I have raised my cables on lego blocks etc. That meme has poisoned the well and it is hifi industry to blame at least partially
You could still get a decent system for that (grand for source, amp, speakers = $3K but then the next step up is like $3K per component.
But I've found that 3 grand is still too expensive for most people, They might be able to afford it but they don't want it bad enough to pay out that kind of money.
Most civilians have an idea of pricing that they have got from looking in the window of a boutique hi-fi store or from an audiophile friend who has spent big money. The s/h market where the real bargains are is totally unknown to them, even if it isn't then they are overly wary of buying used electronics.
I have friends say 'This sounds great but you spent a fortune, right?' When I say no, 2 grand, they are surprised but it's still too much for them to contemplate splashing out on something to play music on.
A friend asked me to help him get a system but he refused to buy used kit. I said 'Well in that case you will need at least £2K for what you want' - nope, too much so he left it. He earns about £100K a year.
Another friend a bit more experienced (former EE and recording engineer) moved here from SA, couldn't afford to ship his possessions so sold his hifi before he left. Came round mine and picked out a system from my collection - TT, CD, amp, and some KEF Calinda speakers. Total cost £170. I threw in some cables for free,
He invited me round for lunch and a listen. Has the speakers set up in a large concrete room. I tell you now, I know audiophiles who have spent tens of thousands and who would weep at how good that sounded on all sources. But I've found you just cannot convince most civilians to go down that route.
