£156 is slightly above the bargain end of the used range for a PM340, but still looks fair rather than ambitious. Recent market sightings put one around £50 in rougher local listings and about £150 in a confirmed working sale, so £156 sits in the sensible middle for a clean, functioning example rather than a steal or a stretch.
That’s a good place to be with this model, since the PM340 is a solid late-80s/early-90s Marantz integrated with the easy, musical presentation people buy old Marantz for. At this price, the appeal is more about a straightforward, well-regarded vintage amp that should pair nicely with efficient speakers than about upside/spec-chasing. If it’s been serviced, or at least is quiet and all controls are clean, it’s a reasonable buy.

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.
