In my early 20's, I would consult with high-end audio dealers when they were considering which brands to sell. I didn't get paid for this, but it was still win-win: I got to listen to whatever I wanted, privately, through lots of gear I couldn't hope to afford. In return, they got explanations of what I liked or didn't like and why (and not in that mushy language of "chocolatey bass", "insistent upper-mids", "soundstage of ambiguous dimensionalty), etc.). My goal was to get their brand lineup to the point where everything was of roughly equal very high quality and among the choices, it came down to the customers' own preferences. These stores didn't sell Tice clocks[1] or $20,000 1m interconnects--those places sold more pseudoscience than anything else. My stores would sell you a basic turntable-amp-speakers setup for a few thousand that was head and shoulders better than what you'd get spending the same amount at the big box places. If a customer wanted to go much higher than that, we'd give the names of contractors to build their listening rooms.
I say all that because now that I can actually afford today's equivalent of everything I wanted back then, the hearing loss that runs on my father's side of the family has kicked in. There's no such thing as a soundstage any more, and "pianissimo" is Italian for "drowned out by tinnitus". "High end" audio is when my hearing aids are charged up. :(
