At US$495, this is right around fair market: it sits just above the US$485 median and within the recent US$469–US$496 interquartile band, so it’s not a steal, but it isn’t an ambitious ask either.
That makes it a sensible buy if the amp is clean, original, and functioning properly, because this model is well liked for its muscular, effortless drive and classic high-current Harman Kardon sound. The real upside is value: if it’s been cared for and hasn’t needed recent work, you’re paying near the going rate for a substantial vintage stereo power amp rather than gambling on something obscure. At this price, I’d mainly want confirmation of stable operation, quiet channels, and no signs of protection-mode or aged-cap issues.

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.
