When I moved in with Tina my stereo went into storage, not only due to space issues in a small house but because she doesn’t appreciate the idea of a room organised around listening to music. It can be a problem, certainly, and there’s no denying that having a nice pair of speakers on stands a foot or so from the wall does get in the way. It’s a compromise, although improvements in other ways to enjoy music - primarily digital devices - make it bearable.
I can happily immerse myself in music, sit and listen to it for hours, whereas watching the telly rarely grabs me as something I want to do (when living alone I never bothered with one and didn’t miss it). Because of that the quality of sound matters, as sooner or later you start to feel the boundaries: the slight lack of spaciousness; the instruments hiding in a crowded midrange; the unfocussed bass lines. Audiophile approaches to music, though - a combination of critical listening, wandering imagination, self-deception and a desire to turn hardware into a hobby - are a little beyond me, for reasons of finance, temperament and the acknowledgement that I’m in my fifties and my hearing isn’t exactly going to improve. I want a presentation of music I can enjoy in order that I can get on with loving the music.
With all that preamble in mind, I could probably manage with my current 'phone and earphones - a Google Pixel 3a and a pair of Shure SE215s. Ideally I’d want my external DAC… and the earphones are a bit lacking in places… and I suppose I do already have enough wonderful music to enjoy for a lifetime, especially when better kit means discovering more in each piece… This is why I over-research and over-think things, I’m really quite poor at simple decisions.
I do try to put together the best system I can on a very modest budget, but the music probably wins. Then again, I also research the best versions of an album, trying to avoid the ridiculously compressed offerings which came into vogue a few years ago (General finding: look for old West German CD pressings if they exist for the music you want, which are often quite cheap), which is one reason why I don’t use streaming services.
So, the answer for me is more music. Probably. I think.
