A condition-unknown example at £269 is slightly above the £243 median and just over the £267 75th percentile, so it reads ambitious rather than a bargain. It’s not wildly out of line, but compared with the recent set it’s asking for top-end money without the benefit of a clearly stated condition premium.
That said, this is one of Marantz’s better-regarded late-vintage integrateds: a smooth, musical, easy-going amp with enough current to make sensible speakers sing, and the KI Signature badge usually adds a bit of collector appeal. If it’s clean, original, and fully working, the upside is in getting a respected classic with good tone and solid build; at this price I’d want confirmation on service history, controls, and relay/noise issues before moving fast.

Marantz originated in the United States, founded in 1953 by Saul Bernard Marantz, a music enthusiast and amateur musician born in Brooklyn in 1911. Dissatisfied with the audio equipment of the era, he crafted the groundbreaking Audio Consolette preamplifier in 1952 from his New York home, selling the first 100 units rapidly and prompting the formal establishment of the company in Woodside, Queens. Though production later shifted to Japan in partnership with manufacturers like Standard Radio in 1966, and the brand evolved through ownership changes including Superscope and eventual integration into larger groups, its heritage remains rooted in American ingenuity and a relentless pursuit of musical fidelity.
The brand excels in high-end audio components, particularly amplifiers, preamplifiers, and integrated systems that defined its golden era. Iconic models like the Model 7 preamplifier (1958), Model 9 power amplifier (1960), and Model 10B tuner (1964) set benchmarks for performance, while later offerings expanded to tuners, receivers, and CD players. Marantz briefly ventured into speakers under designer Ed May in the 1970s but focused primarily on electronics rather than turntables, headphones, DACs, or cables, emphasizing separates renowned for their "Most Musical Sound."
Marantz commands a premium position in the hi-fi market, revered as a high-end pioneer that shaped the audiophile landscape through the 1970s zenith. Today, it blends vintage allure with modern elegance, appealing to discerning buyers who value durability, innovation, and warm, detailed sound signatures over mass-market accessibility.
