I can usually always find something that a man at least, spends an inordinate amount of money on, whatever hobby they have, whether it be a 100k boat that they use 3 times a year, 18 old watches, 20k worth of power tools to make an 800 dollar house, etc. So I mention my opinion of his stupidly expensive insane hobby that(dweebs, jocks, motorheads, sex addicts, gamblers, boaters, heroin saleman) seem to find interesting.
When I think that I get to use my hobby 1 to 8 hours a day, it harms nothing but my ears, and how much my other hobby, golf, costs, in time, clubs, lessons, green fees, travel, joining a golf club, monthly fees, etc etc. If I keep the stereo long enough, and buy too many 400 dollar drivers, then the stereo is cheaper :0 not to mention, everytime I listen to a cd, my wife does not get the urge to go to the spa for three hours unlike golf on vacation.
