I tend to work toward a sound that makes my classical and acoustic heroes and folk-rock, sound most realistic, usually involves a mandolin violin and/or a female vocal. The process is a big part of the fun, obvious I know to most of you.
Choosing and placing/adjusting speakers and modding the room when possible is productive and fun.(Walked into a showroom expecting to buy KEF's, walked out with Rega RS3 speakers because the seller correctly though they might do better for what I told him I was after) Re-doing the guts of older electronics is fun and sometimes musically productive, always educational. I like to solder.
I have tried hard to hear differences in speaker cables and can't.
A quality SVS sub helped refine the sound in a big way. Not miraculous, or jaw dropping, just better. I never notice "phase" or "crossover" issues affecting musical enjoyment. And the individual parts are easier to move around for this old back. (Compared to ginormous main speakers)
Ultimately the best way to get the best acoustic sound is to play it yourself with pals, and/or see it live in a "sound friendly" environment.
I got as much "emotional support" and almost as much aesthetic pleasure from recorded music when I was younger and broker as I do now.
Enjoy the ride because soon, you know, we will all be dead.
(and maybe someone else will a get our stuff in a killer deal at auction and carry it on!)
