At £50, this Trio Kenwood A-3X Integrated HiFi Amplifier is a genuine bargain, sitting well below the 25th percentile of £60 from the 386 recent GBP comparable listings where the median is £90. This asking price is significantly lower than the typical used market range, making it an exceptional deal for any enthusiast.
The A-3X is well-regarded for its robust 33 watts per channel output, excellent frequency response from 10Hz to 40kHz, and comprehensive inputs including dedicated Phono, CD, Tuner, Aux, and Tape connections. Its original-owner condition and inclusion of the preamp in/out jacks offer meaningful upside for system flexibility, presenting a clean buying opportunity rather than a warning. With no material caveats at this price point, it is a prime chance to acquire a reliable, vintage hi-fi staple.

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.
