Our Thoughts RADAR AI

At £23, this sits well below the £93 25th percentile and miles under the £118 median, so by your recent GBP comps it looks like a strong bargain rather than a merely fair ask. For a Marantz integrated from a respected era, that is the kind of price that leaves plenty of room for normal servicing risk and still keeps the overall buy attractive.

The PM57 is worth a look because Marantz integrated amps from this period are generally liked for a smooth, easy-listening presentation and solid everyday usability with decent phono-stage potential on many variants. At this price, the upside is mainly in getting a musical, well-built amp cheaply; just verify it powers up cleanly, both channels work, and the controls are quiet, since age-related contact noise is the main thing to check on older amps.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Marantz

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.
