At £160, this Marantz PM66SE is priced just below the median of £162 from your ground-truth listings, making it a fair deal rather than a bargain, since it sits comfortably between the 25th percentile (£132) and 75th percentile (£176). New, this KI Signature model cost £400, so buying it now at roughly 40% of original retail represents solid value for a well-loved vintage amp.
The PM66SE is highly regarded for its clean, open sound and clear bass, delivering 50W into 8 ohms with exceptional low distortion (0.008%). Its KI Signature tuning offers a slightly more open presentation than standard SE units, and at this price, it’s a smart buy for driving most bookshelf speakers like the Klipsch R-51M. Unless the listing notes missing accessories or questionable condition, this is a genuine buying opportunity for enthusiasts seeking reliable, musical performance.

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.
