When I was really little, my first stereo ever was a little boombox, a single piece unit with two small speakers that could play one cassette.
A few years later my parents got me a bigger boombox. This one had detachable speakers, and could play two cassettes.
A few years later my parents got me a cheap used realistic rack system.
-I got those three systems all before the age of 11 or so, and even though they all sucked, I was super happy with each one as it was still an upgrade over what I had before.
A few years later, the rack system I had literally went out with a puff of smoke. I started using my grandfather's old SX-780 at that point. I was still so young, with so little knowledge at that point. At one point I had car subwoofers hooked up as a second set of speakers. The front-panel light on the SX-780 would literally dim every time the bass hit, that poor thing. Amazingly the SX-780 never broke, and is still working great even to this day.
After that, I started using a Fisher RS-1050, along with some
cheap KLH speakers. The KLH speakers were cheap, but they were still a big improvement over everything I had used previously up to that point. The RS-1050 started to develop some issues with it's right channel. One of my mom's friends gave me his old RS-1060. It turned out that the RS-1060 had a broken preamp section. Since both had pre-out and main-in jacks, I ended up using the RS-1050 as a preamp and the RS-1060 as an amp, which worked great for years. That was my first "real" setup because it actually sounded decent, and had the power available to actually get loud. A few years later my Uncle gave me his JBL L150's, and that was the start of the "current era" for me as far as my system goes.
