Used to be ... sort of. I got influenced by a friend who went the Thorens/Linn Sondek/Pink T route, and I sacrificed my virginity to an old but entirely decent Rotel belt-drive, on-board arm, Linn MM/A&R/Goldring MM, Nytech Int/Celestion Dittons, then moved up to a Rega P3, AT sumtink or another high-end MC, Musical Fidelity Int and Naim amps and really old KEF monitors with real wood (not veneer) panels, and last set-up was a Pink T, Syrinx PU3/Decca London Gold, Musical Fidelity Pre and Rotel Power and I forget what speakers.
Can't afford to be anymore - no space and no marnie. Sides, my Pink needs surgery, and I have no idea where my Pre went and I'll need new speakers. LOL!
I think a lot of guys get turned on by the tech/hi performance/aesthetic stuff. For some, it's cameras, hi-fi, or computers, RC cars, real cars, marine aquariums etc. Don't often hear of high performance stree bikes though.
