It is not only about quality, it is also about musicality, tonality and how "natural" the music sounds, that affects if you like the music or not. 24 years back when I got a Bose AM5 Series II (ahem!) system with Yamaha+Kenwood+Technics, I tried some classical and jazz. Somehow I did not like that music and simply didn't care about it. Fast forward 12 years and I set up a real system with Quad+NAD+Marantz and it was a totally different ball game! I started collecting classical and jazz music along with vocals that sounded boring on my previous system. With my current system,it is even more involving.
Point is - if the music sound "natural", you gravitate towards it and love it. Think of what happens when you are out and about, say in a park, or in the streets and you hear a (one man band) person with a guitar or a set of drums. No matter what they play, you stand there and listen intently. Does it matter which genre of music that person plays? At least in my case, I don't care. All I care about how lovely it sounds and how it gets your toes tapping. So, the "better" your system gets, the more you listen to it. Unfortunately that comes at an expense - both - money wise and the quality of recording wise. Poor recordings are laid bare, but at least you can admire the musicality, if not the quality.
