Fair ask, a touch below the median. At US$1,375, this sits under the US$1,431 25th percentile and below the US$1,488 median, so it reads as a mild bargain rather than a stretch. It is not a screaming steal, but the price is close enough to the lower quartile that a clean example should be attractive.
The appeal here is straightforward: this is a respected vintage power amp with the kind of straightforward, no-nonsense drive that made Marantz hardware a long-term favorite. If it’s electrically healthy, a unit like this can be a very satisfying way into classic two-channel sound, especially for buyers who value build quality and a bit of old-school heft. With condition listed as unknown, the real buy/no-buy hinge is whether it powers up quietly, runs cool, and has any service history.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
