YOU ARE BIDDING ON A PIONEER SA-5800 INTEGRATED AMPLIFIER ( AMP ) FULLY SERVICED RECAPPED + LED'SEXCELLENT COSMETIC CONDITION MINT ALL AROUNDLIGHTS UP NICELYEXCELLENT WORKING CONDITIONFULLY RE-CAPPED All electrolytic capacitors have been replaced with Elna and Nichicon Gold capacitors, DC offset and Bias have been adjusted to factory specs and all solder joints re-soldered, unit serviced to new conditionSHIPPING TO USA AND CANADA $65INTERNATIONAL BUYERS MUST EMAIL FOR SHIPPING COSTDescriptionPioneer engineers kept in mind a dynamic concept when the SA-5800 was still in the drawing board stage.The choices of circuitry and design at that stage were based on what has come to be known as our Magni-Wide policy in amplifiers.The policy does not dictate circuitry designs per se; nor does it restrict us to using tried and true circuit parts when something newer (and possibly even less costly) can be substituted without harm to musicality.The policy does set ever-higher parameters in three critical performance areas, however: Dynamic response, Frequency range and Transient response.Techniques of reducing noise and distortion (of many kinds) are employed to achieve these parameters in the SA-5800.SpecificationsPower output: 25 watts per channel into 8Ω (stereo)Frequency response: 20Hz to 40kHzTotal harmonic distortion: 0.03%Damping factor: 30Input sensitivity: 2.5mV (MM), 150mV (line)Signal to noise ratio: 76dB (MM), 98dB (line)Output: 150mV (line)Semiconductors: 3 x IC, 21 x transistors, 18 x diodesDimensions: 451 x 151 x 271mmWeight: 7.3kgYear: 1979
The SA-5800 sits in Pioneer’s respected vintage solid-state lineup, and that makes it an appealing piece for a classic two-channel system. At US$750, this is clearly ambitious against the recent used market: the median is US$199, the 75th percentile is US$466, and this ask is well above even that upper quartile.
What saves it from being a total stretch is the “fully serviced” angle, which matters on an amp of this age if the work was done well and documented. If the recap, LED work, and calibration were done by a competent tech, you’re paying for convenience, lower near-term risk, and a unit ready to enjoy. Still, at this price, buyers should want proof of service and confirmation it runs quietly, switches cleanly, and holds bias/DC offset properly.
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.
