I would contend that you're expanding your horizons music-wise as a side effect of having better equipment, but if you enjoy it, that's what it's all about, isn't it? As others have mentioned it can lead you down a rabiit hole where you only listen to a small selection of recordings that sound good, but I've found that with a better system most music sounds better (or different, at least), and you start searching out more diverse music. I find I'm listening to all kinds of things I never bothered with, like jazz and acappela groups; still can't listen to most classical music or opera, though. Also it could be a matter of getting more nature in your listening habits, but I too have come across albums that I used to play to death in my youth but now are so compressed and such bad quality that it's distracting to listen to. A live album from Journey that I loved is so compressed and lifeless on my better system. I used to listen to Grand Funk Railroad's Live album and I recall my father coming into my room, calling it garbage and stomping out of the room. I just listened to it recently and you know what? He was right - I couldn't even listen to a whole side without yanking it off. I am forcing myself to go through the pile of records that I've picked up recently or have had for years and am giving them a spin, and I'm finding more often than not I'm enjoying them as if they were recordings I'd never heard before, because of all of the extra detail and the instruments and effects that I never realized were there.
Listening to music I don’t particularly like
Do you find yourself listing to music you don't particularly like because it sounds so good on your system? If I'm honest with myself I am an old dude who grew up with classic rock and really enjoy it but a lot of it was not well recorded. So I find myself listening more and more to other genres of music that I normally wouldn't just because they sound so good on my system. I don't know what this says about me, maybe I am more of an "equipmentphile" than a music lover? I keep listening to music ranging from classical to vocal jazz to country and I love the sound of it but it doesn't get my toes tapping like a good old rock song from my youth. I was even listening to Chinese drums today. Is there hope for me? Will I ever ever enjoy this music as much as I enjoy the "sound"?
