How old are you?

I'm 738 years old (a vampire)

I will be 76 in 3 weeks, had my first stereo system at age 15.

73... And still like large advent speakers.. Pioneer1010 receiver.. McIntosh poweramps

80 years.  I became a budding audiophile in 1956 when I built an Eico HF20 integrated amplifer.  Hooked a cheapo Garrard turntable with GE cartridge to it, and fed it to an Electrovoice 12B loudspeaker that I installed in an Argus bass reflex cabinet.  That got me through my senior year of HS and six years of college.  Went stereo then, and never looked back.

65, going on 72.  No shame in getting older.  No glory in staying young.
