Investments don’t necessarily have to deliver a return financially. In this case, the OP is stating that all of the time and money he has invested through his journey is now delivering value back to him such that he is satisfied for the long term. Simply a distinction between some sort of wealth, which includes happiness and security, and money, which is not guaranteed to.
That said, if I lost a nickel for every audiophile that said “I finally made it… I’m done!”, I’d be out of business. :)
There’s no shame in the chase. Even if we are satisfied with what we have now, we as people change. Our hearing changes, our perceptions change, our tastes change. Gear and technology changes. As a good friend always tells me, it’s about the journey, not the destination.
I myself was in the same boat, which is why I decided to start Bliss Hifi in April 2022. I wanted to invest my time in helping others along their journey. I was already doing so for friends and family, but I wanted to do it more in a professional sense. In a year and a half, I’ve helped hundreds of people find similar value in the way the OP describes. But along the way, I learned even more in the last 1.5 years about my own system and setup than I did in the last 20 years as an audiophile. Even though much of my componentry has remained the same, speakers, positioning, cabling, accessories have all evolved to elevate my system to new heights.
Embrace your progress every step of the way, but stay open minded on where you may continue to grow from where you are.
