I think there is a spectrum in this place. It moves from those who are emotionally engaged with music, and for whom HiFi is primarily a tool, to those for whom the technical dimension is the driver. They gain most satisfaction from a more analytical pursuit of great sound.
Both of course utterly valid, and this is also a gross over-simplification, but I think it has some currency.
My bother and I are at opposite ends.
He loves it when his system sounds great almost irrespective of content. He selects a recording on sound/recording quality and disdains things that are poorly recorded. He is interested in ‘how/why’ and has enormous technical knowledge. He will tweak. He generally plays the same artists and albums, rarely buying anything totally new to him, although often remasters etc. Lyrics and ‘stories’ are relatively unimportant. He describes his system in terms like ‘transparent, dynamic, imaging, timbre’.
I have a primarily emotional response to music. I struggle to give reviews of kit beyond ‘engaging’ or ‘enjoyable’. I enjoy music that suits or builds a mood. 95% of what I buy is new music, probably 50% new artists. I am interested in the ‘who/when’. I appreciate an emotional back story; Leonard Cohen’s last album, weeks before his death, wrestling with religion and mortality for example. To my brother it is the sound of a voice that has ‘gone’. I’d really love a great system that is plug ‘n’ play, and almost never tweak. I’d never choose a demo track specifically on how it sounds, only on how it should make me feel.
My passion is music first, his is HiFi. He loves his listening time and his system journey no less than I do. He buys (different) kit probably more often, swapping things around.
I also think there is something in LindsayM’s comment about cheap reproduction. I can easily remember the most fantastic musical enjoyment dancing around my student room with a cheap cassette radio, or in my car with an appalling quality stereo. For me it is important that the kit never gets in the way. I’m aware that as my system has improved vastly (and as it engages me more) it is also a little more fickle in set up etc. I find this annoying tbh.
My clumsy two penneth. In summary; thank goodness for music, and the means to enjoy it!
