US$190 is above the recent used median of US$149 and the 75th percentile at US$172, so this is a bit ambitious rather than a natural bargain. It is not outrageous if the unit is clean, original, and fully working, but I’d want a little more than average condition or included accessories to feel great about paying that number.
The upside here is that the A-20-S is a straightforward, well-liked integrated with 50W per channel, phono MM support, and a solid reputation for being smooth and easy to live with. At this price, I’d look for remote, original packaging, and proof of careful ownership; otherwise, I’d try to land it closer to the middle of the market.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pioneer traces its roots to 1937 in Tokyo, Japan, when founder Nozomu Matsumoto, inspired by the thrill of imported hi-fi speakers, developed the A-8 dynamic speaker and launched a radio and speaker repair shop. The business formalized as Fukuin Shokai Denki Seisakusho in 1938, evolving into Pioneer Corporation and embodying Matsumoto's philosophy of "Move the Heart and Touch the Soul" through audio innovation.
The brand excels across diverse hi-fi categories, pioneering Japan's first headphones in 1960 with the SE-1 and the world's first component-based stereo system in 1965 via the PSC-5A. Pioneer's portfolio spans amplifiers, speakers, turntables, and DACs, alongside landmark car audio advancements like the 1975 Supertuner-equipped stereo and the 1986 in-car CD player, blending home and automotive excellence.
Today, Pioneer holds a commanding mid-to-high-tier position in the market, revered for reliable, performance-driven gear that balances premium quality with accessibility. Its vintage components attract collectors, while current offerings appeal to discerning buyers seeking robust, innovative sound reproduction without boutique excess.
