How old were you when audio gear first caught your interest?

I was about 20, and it was shortly after I bought my first decent car - a white 1975 Cutlass Supreme w/vinyl roof and blue velour interior.  I installed a crappy Sanyo cassette player, Tancredi booster, and some horrible sounding Jenson speakers....the pursuit for improvement and perfection started there!  

@vetsc5 You’re very welcome! This question came to mind in a fit of nostalgia for what with the perspective of time seems like a simpler era. I have an older sister that was obsessed with Neil Diamond and she often played Neil Diamond records. With her bedroom next to mine I always heard Neil Diamond. There was this one Phil Ochs record too- that started me on a discovery journey for my own music which was a via listening to the radio. My interest in music definitely predates my interest in the gear by a number of years 

My Dad always had a decent system.   When I was 15  I bought my first real piece of stereo gear.  A Sansui AU9900.     I found it in The WantAdvertiser and my Dad drove me out to pick it up.   $300.   

I was about age 28 when I got the bug for nicer equipment. I was married and more settled down. I am now 71.

Born in 49. I bought a kit amplifier I bought in the early 60's. I do not recall the brand but it was not Heathkit. I also bought some speaker kits from them. I do not recall the turntable brand. It was fun building the kit and my first record was a Ventures.
