Kenwood KA-7100 Integrated Amplifier. Unit is overall in good shape and fully functional. Has imperfections and pictures should show those well. Unit had a service in 2021 and has been used sparingly since, receipts is in pictures. Comes with a bound manual, marketing materials, and a service manual. Unit was checked on 6/12/2026 Bias 19Mv and Offset 2Mv. Switches and knobs all quiet and smooth.I have not polished the faceplate or cleaned the inside. So pictures show it current state and condition. If you are wanting this unit restored, I can do that for you as well. This unit looks to be all original, case screws still have clear plastic washer on them which is a sign probably was not messed with much. Any questions feel free to message me.
At US$395, this looks like a strong buy: it sits comfortably below the US$421 25th percentile and well under the US$494 median for recent comparable listings. For a classic integrated from the Kenwood sweet spot, that’s the kind of pricing that usually leaves room for a sensible service budget if needed.
The appeal here is straightforward: these are respected, straightforward amplifiers with a good reputation for musical, punchy sound and solid build quality, and they’re still very usable in a vintage hi-fi system. If the unit is clean, switches quietly, and both channels behave properly, this is the sort of listing enthusiasts should move on; just confirm it’s been tested thoroughly and that no major work is lurking if the seller can’t document service history.

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.
