*US* BUYERS IGNORE MESSAGE ABOVE SAYING THERE IS TARIFFS FOR THE BUYER THAT IS NOT TRUE! I PREPAY ALL US BUYER TARIFFS NO TARIFFS FOR YOU TO PAY, YOU PAY IS ONLY AT CHECKOUT NO HIDDEN FEES* Unleash the power of high-fidelity audio with the Harman Kardon PM640 Vxi Amplifier, a testament to the golden era of the 80s. This integrated amplifier, crafted in Japan, boasts a robust 45W power output, ensuring your music and audio are delivered with clarity and depth. Its sleek black finish complements any home audio setup, offering an elegant, retro aesthetic.The PM640 Vxi is equipped with 6 inputs and 2 outputs, catering to a variety of audio sources. It supports stereo L/R RCA connections, along with raw cable speaker jacks for a direct, unadulterated sound signal. The amplifier's dual-channel setup is designed to perfection, mirroring the legendary sound quality Harman Kardon is renowned for.
This is a seller’s market at this price: USD 353 is clearly above the recent comparable range, exceeding the USD 305 75th percentile and sitting well above the USD 250 median. Unless it has been professionally serviced, includes unusually strong provenance, or is exceptional cosmetically, this is an ambitious ask rather than a bargain; a more convincing target is roughly USD 200–305.
The PM640 VXi is a genuinely capable vintage integrated, with a lively, warm presentation, a useful MM phono stage, and a stout high-current power supply that makes its 45 watts per channel more authoritative than the number suggests. It is a good match for many moderate-sensitivity speakers and remains appealing as a simple two-channel setup. At USD 353, though, the buyer should insist on fully demonstrated channel balance, quiet controls and switches, clean speaker outputs, and evidence of recent service—otherwise there are better-priced examples to wait for.
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.
