The struggle for me is always how much gear to have and how much to spend. I don't mind mid-fi, but I tend to aim for top of the line gear, or at least gear that was really expensive when new.
I realistically have 3 spaces to listen to music - downstairs living room (main system), upstairs living room, and office.
Also, I work from home, so I get more than 40 hours/week to listen to my gear.
And I also use the stuff in the two living rooms for TV and home theater...so my stuff gets a lot of use, typically!
Where I struggle is "stopping"...just having 3 systems and being done. I, like many here, like to experience a variety of sounds and a variety of gear. So I'm always looking for a good deal, or "the next thing."
Well, that has actually led to a lot of gear swapping, and getting rid of things I wish I still had, and "choice anxiety" (it all sounds good, so what to keep?!?!) It's almost made this hobby more stressful than fun.
One thing that helped is switching from separates to integrated amps w/DAC's built in. Less boxes, less temptation for upgrade-itis. Also less cables and clutter.
So, right now, I'm trying to pare down to just the 3 systems, and unload everything else. Just run with what I've got and be happy. I've got a few amps to get rid of, and 3 large pairs of speakers, and one pair of large empty speaker cabinets. I'm going to enjoy all of the gear while it's still in the house, but I won't miss it when it's gone. It's taking up too much space. I haven't been able to hang my guitars on the wall in over a year...or hang up the dart board (had to take it down because the speakers are in the way!)...and ideally I'd like to put in another bathroom where...you guessed it...I'm currently storing speakers.
So for me, it's 3 good systems...mid-fi or hi-fi...whatever I can afford...whatever is "good enough"...whatever I can be content with. No more hoarding and no more of the "choice anxiety."
Not saying I'll never start gear-swapping again or that I'd never go back to separates...I just want to take a break for a few years...focus on the music and other hobbies...and then re-visit.
I don't know if I've even answered the question, but for me, it's about having "just the right amount" of gear, for every space where it will realistically be used, and not a bit more.
