The stereo “salons” I frequented didn’t offer “high-end” components. (I auditioned McIntosh, but I bought Marantz, PL, Technics, ADC, Bose 901s.) I’m guessing the people who made the distinction between hi-fi and hi-end wouldn’t probably have seen McIntosh as making the cut(?). But I don’t know.
A wealthy snob-friend of mine, in 1983, laughed and rolled his eyes at my Marantz separates/Bose system—as well as all things McIntosh. Although he didn’t even own a hi-fi (and he didn’t use the term “high end”), he said he would only buy Mark Levinson, Conrad Johnson, and Audio Research.
I know individuals like that... I am not, at all, a fan of Bose, especially the stadium-lights inspired 901s, but for those who like them

Marantz is a great manufacturer, that has produced wonderful products over countless years... Mark Levinson, Conrad Johnson, and Audio Research are also phenomenal for the most part. I have this saying: Buy the best you can afford, with in reason, and you will not be disappointed. I could probably swing Mark Levinson, Conrad Johnson, and Audio Research products if I go on a strict no-food, water only diet, and turn-off my air conditioner completely... I simply do not wish to afford them. My father-in-law, who is a quite wealthy man, has gotten back into stereos several years ago. He has a Mark Levinson SACD player. It's extremely nice... But, in all honesty, I cannot hear the difference between it and my Marantz SA-8005. My Marantz I purchased used three years ago, and it was 1/10th of what Paul paid for his Mark Levinson.

The whole thing is like someone, well, like my sister: "I drive a Mercedes-Benz." with her nose-up in the air, while I drive a little Nissan truck. Her Mercedes, although it's a lower line model, is very nice, and has that fabulous three-pointed star... YET, I get my husband to change the oil in my Frontier for around $20-25 or so, while she just complained to me spending $199.99 for an oil change at Mercedes. I told her: Well, if you can afford a Mercedes, you can afford the maintenance (at least she does the maintenance).
