ZelleSony SQA-200 Quadraphonic Decoder / Amplifier (1970s) A beautiful relic from the brief, ambitious era when audio companies tried to surround you before surround sound was even a thing. This is the Sony SQA-200 — part of the original quadraphonic movement. Designed to decode SQ records and power rear channels, it turns a standard stereo setup into a 4-speaker listening experience the way engineers imagined it 50 years ago. I have two available, both in matching vintage condition with that warm brushed aluminum face and walnut cabinet that makes mid-century hi-fi so addictive. These aren’t just components — they’re conversation pieces. The kind of gear that makes people stop mid-sentence and ask, “what is that?” Perfect for: Vintage hi-fi collectors Quadraphonic enthusiasts Studio decor or listening room builds Anyone tired of black plastic boxes with no soul? My vintage audio gear is stacking up faster than I can sell it. I'm selling the bundle buy one get one free on the decoder and throwing in the KLH model 22s as a nice gift.
