This is a very interesting discussion. We do hear things differently, and we also value different things.
I value having access to so many different pieces of music and artists and being able to enjoy them in so many different ways - stereo audio, multichannel, concert video, through tubes, SS gear, planars, cones, subs, no subs, etc. In that way I don't necessary have a preference for one sound (although in general there is a gear configuration with my planars that I love the best) but rather enjoy tuning and configuring the system to best fit the media. That's when I realize I've been being called to dinner for 30 minutes.
I had an interesting experience a few months back. My good friend has a pair of KEF R3 speakers he'd be talking up, and he wanted me to fly down to have a listen (and for his birthday, to be fair). I said I'd come if he'd finally bite the bullet and buy some cost-effective separates to replace the Yamaha receiver he'd been using for 2 channel.
When I arrived, he still had the KEFs on the Yammy and kept asking "don't they sound great?" I could hear some pretty tones - felt the tweeter had some potential -- but I felt I could hear some form of stuffiness or compressive quality in the midrange and high bass. The detail wasn't there, more like a traffic jam of sounds. He had the sound running from his Firestick (!) to his TV via HDMI (!) then through the ARC (!) to the Yammy (!) then out to his speakers. I feared I had some expectation bias given that awful signal path, and maybe was just confirming that with my feeling on the sound.
When we got the separates in place, it was no comparison and he could hear it too. Everything was crisper and that traffic jam feeling I had was gone.
OK that's a good story about improving sound from a terrible signal path. But what has stayed with me has been the question about what I heard in the before and after and how it wasn't frequency response, or volume, or timber, or even rhythm. It was something else, and something I don't think I could have heard had I not spent the last 10 years listening to my system. And I wonder what the exact differences were (albeit obviously the difference was vast) between the two signal paths that created such dramatic results.
Compared to our other senses, we don't have a good lexicon to describe what we hear. And that goes not just to language but I think to our brains which don't do as well phenomenologically with audio as with our other senses. We tend to use metaphors like "bright." And in many ways the auditory memory seems more fleeting. While the sense is there - I could clearly detect the traffic jam feeling -- pinning it down, describing it, analyzing it, permanently retaining that aspect, quite difficult.
That's why, in the end, it does have to be all about the music.
