I have never understood the obsession with recording or production quality.
I don't care if the music sounds like it was recorded in a garage on a fifty quid tape deck. For me that sound is inherent to that music, it's part of it, it's how it is meant to sound.
I bought a hi-fi to listen to music I like, I don't buy music to listen to the hi-fi. If the production values are high that's just a bonus. I've never bought music or listened to music solely because it is 'well-recorded.'
Example - Boston 'Third Stage' - on parts of it you can hear the tape wow. But that's inherent to the sound of the recording so I don't care. If my system was introducing that wow - or some other colouration - then I would care and do something about it. That's why I don't bother with vinyl anymore.
I think you are looking at the issue a bit too simplistically.
People appreciate good sound quality. That's one of the reasons people buy better sound systems. If every source sounded like a clock radio, no one would care about buying Revel Salon speakers or whatever.
But sound quality is first decided by the quality of the source. So it makes sense that people will appreciate a source that provides good sound quality. That doesn't mean one demands it, or only will enjoy sources with good sound quality, but that it is appreciated and enjoyed when it's there.
I love the beautiful rich quality of live symphonic instruments. Why wouldn't I also enjoy when I hear similar qualities from an orchestral recording, rather than a terrible, thin, artificial-sounding version? If you had a choice would you rather hear an orchestra in a great sounding hall, or something the with acoustics of a public bathroom stall?
Why are musicians so particular about choosing the quality of their instruments? Whether it's a classical violinist or a folk singer choosing his acoustic guitar, or an electric bass player choosing his bass, strings, cabinet etc? Because tone and quality matters, it's part of the music.
The sensuousness of the sound is for many part of music. With a really bad sounding harsh/thinned out recording one can certainly still hear and enjoy the music - I even enjoy music on my iphone's speakers - but with a high quality production/recording you get the music AND the sensous quality of sound, tone, timbre (and likely more authentic/accurate reproduction of the instruments).
So it's a mistake to think that someone who appreciates good sound quality in a source only does so because he's therefore listening to his system rather than the music. No, they appreciate it for the same reason one would appreciate the better acoustics of hearing music in a good room vs a really terrible room. They care about the music in both cases, but it's even better with the better sound.
Now, on the other hand, I can also sympathize with your point about how you just appreciate whatever you listen to on your system. Ultimately, while I certainly do love it when I hear excellent or life-like sound quality, I also enjoy the differences in sound and production character. In fact as someone who collects a lot of old library/production music, the sheer crazy variety in production style and quality from track to track is part of the fun. Sometimes a drum set may be recorded very present, big, powerful and sound almost "real," while in the next track the drums are waaay back in the far left soundstage, like they were recorded with an iphone in a vocal booth. I don't want everything to sound the same, either.
