*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*The Kenwood KA-5700 Integrated Amplifier is a vintage audio piece known for its high-quality sound and durability. With its LED light upgrade and full fresh service, this amplifier is sure to deliver an exceptional listening experience. The Kenwood brand is well-known for producing reliable audio equipment, making this model a desirable choice for vintage audio enthusiasts looking for top-notch performance and sleek design.
For a vintage integrated from this era, timing mostly matters because you’re buying a classic design rather than a current spec race, and at US$384 this one lands below the US$450 median and even under the US$450 25th percentile, so it reads as a strong deal. It is not “too good to be true” territory, but it is priced like someone wants a quick, sensible sale rather than top dollar.
That makes it worth a close look if you want a solid, straightforward amplifier with the kind of warm, punchy Kenwood charm that still has plenty of fans. The upside is simple: if it’s clean, fully functional, and hasn’t been abused, you’re getting a respected late-70s/early-80s piece for less than the going run-rate. I’d mainly want confirmation of quiet controls, stable channels, and any service history, since age is the real variable here, not the asking price.

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.
