When I lived in L.A. I'd try to get to every audio show within a hundred miles. I made myself a nuisance at every high end dealer in the area, and purchased gear at nearly every one. For a while my wife worked for Todd Garfinkle of MA Recordings and I'd be able to tag along to the gigantic trade show in Vegas (what was it called again, CES?). When I was a kid I'd go with my dad to the yearly High-Fi show in Downtown L.A. It was there where I first heard Stereophonic Sound and later Quadraphonic.
What can I say, I have a genuine jones for well-recorded music.
