My interests are broader than hi-fi and records- which activities wax and wane depending on a lot things. There have been periods where I didn't set up a system; others where I'm crawling around on the floor troubleshooting, doing album shoot-outs or tube rolling.
My career was as a copyright lawyer and I did a lot of catalog deals so I know how the industry was structured. A lot has changed.
And my real interest is the history of the technology and the changes in music over time. So I've been beefing up my chops on archival/preservation and am going to try to go back to school- I would be 70 years old by the time I start the program.
I'd say it has consumed a large part of my life but not just as an "audiophile" or record collector.
