The MA700 is a notably muscular THX Ultra monoblock: a serious 200-watt-per-channel-into-8-ohms design rather than a modest hi-fi amp. At US$350, this is a fair-to-good buy, sitting just under the US$353 median and comfortably within the recent US$335–US$389 market band. It is not a bargain by the numbers, but the price is well judged rather than ambitious.
Its appeal is straightforward: substantial current delivery, controlled bass, plenty of headroom, and the flexibility to run difficult speakers or build a multi-amp system. Bridging a matched pair can produce 600 watts into 8 ohms, which gives the model useful upgrade potential. Since condition is unspecified, confirm quiet operation, clean relay engagement, functional level control, and that the rear terminals and RCA connections are sound; at this price, a tested example would be worthwhile.
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.
