I always refer to myself as an audiophile. Someone crazy enough to put enormous effort and money into the endless pursuit of perfect reproduction of music. It’s a clinical term. I am afflicted with it.
It isn’t a bragging term as over my lifetime, in any 10 year period, no more than ten people ever saw it, let alone listen to it. It is a very solo affliction.
One fun test when I was in my twenties was does your stereo system cost more than your car. That has been true for my entire life... even when I got a Lexus, then two cars... and it now cost more than my first house.
