My experience has been the opposite- when I was young, there was a thriving audio community in Pittsburgh in the late '60s and early '70s where I was in school, lots of hobbyists who would get together, the hi-fi thing being the common theme for socializing. When I moved to NYC in 1981, it was burgeoning with stores, both gear and record stores and I met lots of folks, fortuitously, the woman I would marry worked part time for a "golden ears" who was the backbone of the NY Audio Society. That fellow, Chuck Lamonica, was a wonderful, generous spirit and the meetings, usually held at a member's house in Rye, NY, were a hoot. We would have a yearly dinner with the Chinese Audio Society at a big dining hall in Chinatown where the Asian guys would order the craziest stuff to see if us gringos would eat it. Met the guy in charge of used records at Tower on Lower Broadway and when records were being phased out, bought tons of stuff with his help and made regular trips to the Princeton Record Exchange.
Time passed, I had less time for audio, spent a fair amount of time with fast little Italian sports cars and had a similar experience in attending events, meeting people and socializing.
Moved to Austin, starting in 2012 as I began to phase out of my law practice and though I met a few audio enthusiasts here, I don't regularly participate in any events, frequent any retail establishments but on occasion, do travel to Dallas to visit with Albert Porter.
I guess I'm the opposite in that my world has "shrunk" as I've gotten older. I'm now in my '70s, still avidly listen, have a substantial record collection and do converse with like minded people, but much of it is remote now, not in person. Part of that may be age, part of it may be how our culture works now with the Internet being the glue rather than in person encounters.
I think you are asking the right questions. Don't know if there is an audio group near you or a retail store where you might find others pursuing your interest. I think in some ways, though I was a pretty focused listener and serious buyer of some rare records, the social part of the hobby was in some ways the most important.
Sadly, too, as I've aged, I've lost friends with whom I shared some of these experiences. I'm ok being a bit of a hermit but it isn't the best approach to living a full life. I leave in a couple hours for a driving event in the Ozarks, where I expect to meet some new friends who share a common interest. I do think a lot of us don't talk about loneliness, isolation and life enough-- it is certainly an issue for people as they age. I can only encourage you to reach out and try to connect through whatever means you can, including this board-- the "community" aspects are rewarding both as a recipient and as a contributor.
