The Marantz PM6010 OSE KI Signature is a respected Class AB integrated known for its warm, detailed sound and Ken Ishiwata’s tuning, often sought by enthusiasts wanting solid value without sacrificing tone. At £287, this listing sits just below the £294 median from 822 recent GBP comps, making it a fair deal in the current used market—not a bargain, but solidly priced for a well-maintained unit.
This model delivers smooth high-frequency response and tight bass control, making it ideal for vocal-centric and jazz playback. Its KI Signature pedigree adds genuine appeal, and at near-median pricing, it’s a worthwhile buy if condition is clean and the remote is included.

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.
