Throughout high school, I used a Sanyo JA-220 integrated amp and whatever Sanyo speakers came with it in the System 220 package. My mom bought the whole set new in the early '80s with a tuner, cassette deck, and turntable that I didn't use. I used a crappy Gemini that I bought new for $100 in the summer after 8th grade and went through a lot of different CD players that I acquired cheaply. Most were Pioneer 6 disc changers, which I got hooked on after my uncle gave me a PD-M70 back in junior high.
The earliest picture I can find does have the Sanyo, although it was barely ever used at this point. It's from early 2010 during my 2nd semester in college.
The Sanyo JA-220 and the speakers are there, along with the Gemini TT-01. There is also a Pioneer VSX-305 with Yamaha NS-AP4400M speakers set up that I used the most. A Pioneer PD-M401 6-Disc was hooked up to that. There are some Bose Model 21s that rarely got used. I can't remember if they were set as the B speakers on the Pioneer or hooked up to that H/K receiver under the silver Sanyo.
The only things still in use in this picture are my Pioneer BDP-320 Blu-ray player that is in my main setup and my Pioneer CLD-2600 LaserDisc player that is in one of my other setups.
Shortly after that setup, I bought a Pioneer SX-205 because the VSX one was starting to act weird, acquired a VSX-3000 (which was pretty bad), and I bought some big early '90s Pioneer CS-G703 speakers. Then, in the summer of 2010, I finally got a decent turntable when I bought my Technics SL-1700. Around that same time, I joined this site.
After joining AK, I started getting better equipment. At the end of 2010, I got an SX-750, a PD-M900, and some KEF 104aB speakers. In the fall of 2011, I got an SL-1200MK2 and a CT-W910R. These five things that were purchased after joining AK are what make up my current system. I probably wouldn't have a system this much better than what I had in the past if it wasn't for this site.
