I love this topic. It really demonstrates so may ways to approach the hobby.sure.
only speak for my own journey, for sure i was targeting the point of my work retirement to wind down my planning for new things. and reach a stable listening enjoyment spot. i had a few irons in the fire that needed to play out and which did do that. i'm passed my end point with the various parts of my system and media inventory building.
would i use the word 'goal'? that's reasonable. 30 years in.......it's time. but no thinking about not continuing my serious listening and participating in the hobby culture. that is who i am and part of me. i'll still lust after gear and window shop mentally. why stop?
it's reasonable that system building would have an end game. reaching that you have various choices. you can (1) redefine your direction and chase that stuff, even (2) explore new system philosophy choices, or just (3) put it in cruise mode and listen and enjoy. all valid directions.
i'm solidly in #3, but reserve the right to reconsider. if were to downsize my home, that could trigger some changes. and opportunities. it could happen. a few buyers have made offers on my speakers, which i declined. if they upped their offers i might consider that. so that is possible but unlikely. and i'm fully satisfied with my speakers (a high bar to even equal let alone improve) but new one's might be fun (change for change sake). then i would need to re-tune the room (daunting idea). much easier to stand pat.
I have never heard a system that could extend my suspension of sonic disbelief for more than a second, ot two. So, every system ends up being a compromise, even 'no compromise' systems!
No matter how terrific a piece of gear or system or room might be, none last beyond an initial instant of 'could this be it?' before settling in to 'nope, but not bad.'
So, from that vantage, I can never be done. I will always be looking for a way forward on that front.
Then, no matter how good a system is, the way it falls short of reality will be the same over time. I think I habituate and eventually move on from any system because it will always do what it does in the same fashion, day after day.
Even sonic success from artist to artist, recording to recording, genre to genre can be almost impossible to achieve.
So, I end up eventually facing some sort sonic ennui, and I start to notice the roving in my eye.
I love this hobby and search out new stuff to hear, but since nothing ever sounds like "mission fully accomplished" I don't think I will have a true "done" point. (I have plenty of "close enough" sonic toys, and I will rotate things in and out for fresh perspectives, but nothing has ever managed to make me think I am experiencing 'final destination' musical performance.)
None of that is meant in any contentious way, and I will go so far as to say this chase can be completely circular...sometimes our pursuit brings us back to where we were in the past and we 'reappreciate it' again before we pack up and move on again.
Maybe Hi Fi contains it's own version of "The Razor's Edge?"
