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

"I'm right with you there! Lots of people though and because of municipal services reaching areas that couldn't previously be developed we're using up land fast."

Protect your precious plants. In 1978, when I bought this house, we had zero deer in my neighborhood, before they developed adjacent Scotch Plains. Now they are here and everywhere throughout our neighborhood every day, they like my back yard, often 6 of them resting there. 

We had a bad winter, Ice on top of 10" of snow, which was on top of prior 12" of snow. They ate all kinds of things they never ate before, azaleas, rhododendrons, forsythia, including bark of trees. They chewed our Hydrangeas down below ground level.

My father was a passionate audiophile who began his journey in 1948 with a single Altec 604B speaker. Growing up around his hi-fi system, I was exposed to high-quality sound from a very early age.

My own first stereo system appeared in my bedroom when I was 14, in 1967. It consisted of a used Marantz 8B amplifier, a Rek-O-Kut turntable, a Dynaco PAS-3X preamp that my father built, and a pair of JBL speakers.

Teenage electronics nerd in 1960s. Best friend and I would harvest Buick/Pontiac/Cadillac car radios available from junk yards for a few bucks. The audio sections were push-pull 6V6 with a heavy audio output transformer. To use these in our home "hi-fi" we had to power them on 120VAC. So, we'd build power supplies using power transformers from old Philco/ Zenith radios; these delivered 6.3 VAC for cathode heaters of car radio amp tubes, 5VAC for cathode heaters of the full-wave vacuum tube rectifier, which in turn provided filtered [choke and electrolytic condenser] higher DC voltage ["B+"] to the car radio amp tubes. 
The push-pull 6V6 amps put out 12 -20 decent watts that drove our home-built bass-reflex enclosed speakers, using drivers we'd got from Radio Shack, Allied, etc. 
Since then, gone thru AR3a, Dynaco amps, McIntosh, K-horns, B&W, Anthem... 
 

Wow I was about 12 yrs old. My dad was in the Air Force in Thailand. He sent back a Sony reel to reel. He sent me tons of music on reels. About a year after that he sent me a JVC tuner/table combo unit with speakers. It had a 4 band EQ and quad capabilities. It was a whopping 47 watts and I LOVED it!

From there He got me a pair of Sansui (I think 5 way) speakers. Then I saved up and bought a Marantz 1150D integrated and a 10 band Souncraftsman EQ. A Marantz 6501(i think was the model number) turntable with a Goldring cart. From there I lived to read mags,literature, listen to anything at a store.It has never stopped. Now between money and liking what I have I spend every day listening and enjoying music.

It was 1986 and I was 24. I was in the Navy stationed at Norfolk, VA. when I walked into a HiFi store and they were playing Mannheim Steamroller's Fresh Aire 6 on Mark Levinson gear connected to Acoustat panel speakers. Is that weird that I remember the exact event? Anyway, I was hooked after that.
