This is a fair-to-slightly-ambitious ask at US$209: it lands above the US$187 75th percentile and well above the US$145 median, so it is not a bargain-price listing. It can still be reasonable if the unit is exceptionally clean, recently serviced, or comes from a careful owner with strong presentation and proof of function.
The KM-991 is a respected Kenwood power amp with the sort of solid, no-nonsense drive many vintage hi-fi fans like for efficient speakers and honest listening. At this price, the value really depends on condition and service history: if it is original, quiet, and fully healthy, it is a worthwhile buy; if there is any channel imbalance, scratchy controls, or unclear repair history, the premium gets harder to justify.
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.
