At £200, this Kenwood KA-6004 is a genuine bargain, sitting well below the typical used market range of roughly £260–£380 for units in working condition. Recent sales show a UK buyer securing one for around £175 (€175) with minor button non-originals, while restored or pristine examples in Europe command €399 (approx. £340) and US listings hover near £380. This asking price lands near the 25th percentile, making it a strong deal for a 40W/ch vintage integrated that’s highly regarded for its clean sound, robust build, and useful features like dual phono inputs and pre-out/main-in.
The KA-6004 is well-loved among vintage enthusiasts for its reliable solid-state design, warm yet detailed audio, and classic 1971–72 Kenwood styling. Its 40 watts per channel (8 ohm) is plenty for most bookshelf or medium floorstanders, and the inclusion of tone control, loudness, and tape monitoring adds real flexibility. If this unit is from an original owner and powers up cleanly, it’s a smart buy at this price—no need to hesitate unless the meters are dead or switches are broken, which are known but fixable issues on this model.

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.
