Kenwood KA-5700 Vintage Stereo Intergrated Silver Faced Amplifier Tested. VU METER LEDS/LIGHTS DO NOT WORK. Minor Wear From Use & Age See Pics.
With condition unknown, a US$450 ask lands right on the median of recent comparable listings, with the same figure as the 25th percentile and just under the 75th percentile. That makes it a fair, market-level price rather than a bargain, but it is not ambitious either.
The appeal here is the usual Kenwood sweet spot: a straightforward vintage integrated that’s generally liked for solid build, easy usability, and an honest, un-fussy sound when healthy. At this price, the real upside is getting a clean, original, well-functioning example rather than chasing a rare collector piece; if it has been serviced, includes original knobs/cosmetics, or comes from careful ownership, that adds meaningful value. Without those details, I’d mainly be checking pots, switches, channel balance, and whether any service history is documented.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Kenwood traces its origins to December 21, 1946, when it was founded as Kasuga Radio Co. Ltd. in Komagane City, Nagano Prefecture, Japan, by a group of entrepreneurs led by William "Bill" Kasuga. Emerging in the postwar era, the company initially produced electronic components and amateur radio gear, renaming to Trio Corporation in 1960 before adopting the Kenwood name in 1986 to appeal to Western markets—blending "Ken," a familiar name across Japan and America, with "Wood" evoking durability and Hollywood. This rebranding fueled rapid international growth, starting with a U.S. office in Los Angeles County in 1963.
The brand built its legacy on high-quality audio and communications equipment, excelling in home hi-fi amplifiers like the acclaimed 1970 Supreme 1 multichannel model, receivers, tuners, and speakers with innovations such as polypropylene cones. Kenwood also pioneered car audio systems, including the first audio/video amplifier for home theater in 1981 and anti-theft cassette decks, alongside professional two-way radios and amateur transceivers. While maintaining roots in consumer electronics, it expanded into automotive infotainment.
Today, as part of JVCKENWOOD since the 2008 merger with JVC, Kenwood holds a solid mid-tier position in car audio and professional communications, prized by enthusiasts for reliable performance and aftermarket upgrades. Its vintage home hi-fi gear from the 1970s and 1980s commands respect among collectors for robust build and warm sound, though it no longer dominates pure hi-fi markets.
