Offered is „KA-9100 DC“ by Kenwood as second-hand device from the category „Amplifier (incl. Surround)“ on audio-markt.de - the online market place for high-end. The advert with the number 4596073263 ends on 21.10.2026 at 17:26 o'clock.
This is a respected late-’70s/early-’80s integrated with real muscle and a strong reputation, and at €280 it lands just under the €289 25th percentile and a touch below the €298 median. That makes it a strong buy rather than merely fair, especially for a clean example in good condition.
What keeps people coming back is the solid, authoritative presentation and the sense of build that Kenwood’s better KA pieces are known for. If the unit is electrically quiet, switches cleanly, and the controls have been serviced or at least exercised recently, this is the kind of vintage amp that can reward a system for years; at this price, I’d be looking closely at cosmetics, channel balance, and whether any service history is documented.

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.
