It stands as a testament to the enduring legacy of Harman Kardon's commitment to high-fidelity audio. Whether you're a seasoned collector or someone who appreciates the nuances of vintage sound, this receiver is sure to be a standout addition to your system.
At US$807, this is an ambitious ask rather than a bargain: it is well above the comparable-market 75th percentile of US$343, against a median of US$174. “Fresh Pro Service” and genuine rarity may justify a premium, but the listing needs unusually strong documentation to support anything near this level.
The 800+ is a desirable vintage quad receiver, with built-in CD-4 and matrix decoding, useful tape/AUX connectivity, and roughly 50 watts per channel in stereo or 22 watts in four-channel operation. It is a particularly interesting choice for a collector who wants authentic quad capability rather than a conventional stereo receiver. Before considering the price, verify exactly what was serviced, request test results for all four channels and decoding modes, and confirm the original controls, meters, cabinet, and speaker outputs are intact.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Harman Kardon traces its origins to 1953, when Dr. Sidney Harman and Bernard Kardon, both engineers frustrated with conservative audio manufacturing at the David Bogen Company, invested $5,000 each to launch their venture in Westbury, New York. Their debut product, the Festival D1000, became the world's first compact AM/FM hi-fi receiver, blending breakthrough technology with sleek design to make high-fidelity sound accessible beyond technical enthusiasts. Pioneering innovations like the 1958 Festival TA230 stereo receiver, the 1959 Citation II ultra-wide bandwidth tube amplifier, and the 1970 CAD5 hi-fi cassette recorder with Dolby noise reduction cemented their legacy in simplifying premium audio for the home.
The brand focuses on integrated receivers, amplifiers, tuners, and speakers that emphasize performance, reliability, and elegant industrial design. Over decades, it expanded into home theater systems and automotive audio, powering systems in vehicles from Land Rover and BMW to Volvo and Polestar. While not delving into turntables, DACs, headphones, or cables, Harman Kardon prioritizes cohesive hi-fi components that deliver warm, detailed sound without unnecessary complexity.
Harman Kardon holds a solid mid-tier position in the hi-fi market, renowned among knowledgeable buyers for its enduring quality and value rather than ultra-high-end exotica or vintage collector status. Now part of Harman International, it appeals to discerning listeners seeking dependable, stylish gear that echoes its innovative heritage without commanding boutique premiums.
