This is a buyer’s market at US$300: it sits well below the US$375 25th percentile and far under the US$450 median, so this reads as a strong deal rather than just a fair ask. Against the recent comparable spread of US$375–US$524, the price has real upside if the unit is basically intact and not hiding issues.
The appeal here is the Citation Twelve’s reputation as one of Harman Kardon’s better early solid-state power amps: clean, neutral, and capable of real drive when healthy. For a vintage piece like this, the upside is in originality and service history more than cosmetics, so confirm it powers up properly, runs quietly, and hasn’t been hacked around inside. If it’s clean and unmolested, US$300 is very buyable.

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.
