At US$300, this Marantz MA500 monoblock sits right at the market median of US$299, making it a fair price rather than a bargain or an ambitious ask. The 25th percentile is US$155 and the 75th percentile is US$537, so US$300 is squarely in the middle of recent comparable USD listings. While one user noted paying under US$100 used for similar units, the current asking price reflects today’s typical used market value in USD.
This amplifier is well-regarded for its smooth, warm sound with detailed clarity, and its monoblock design offers flexibility for multi-channel or high-power stereo setups. As a THX-certified version, it delivers reliable performance that enthusiasts still trust. At a fair price with unknown condition, it remains a worthwhile buy if the unit is functional and includes basic accessories, representing a solid opportunity for a fellow enthusiast seeking proven, vintage hi-fi power without overpaying.
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.
