Versus a new multichannel power amp or a fresh AVR at this money, this is a pretty sensible way to get real external amplification for home theater or a modest 5.1/7.1 setup. At US$560, it sits above the US$384 median and below the US$774 75th percentile, so it reads as fair-to-strong rather than a bargain; not cheap, but not out of line for this class of gear.
The appeal here is straightforward: Marantz’s MM7055 is a respected 5-channel Class AB amp with honest current delivery, a clean, unforced presentation, and enough headroom to take pressure off an AVR. It’s the kind of piece that makes sense if you already like your processor or receiver and just want more muscle and better control. If the unit is clean, fully working, and has been treated well, this is the sort of used amp that can be a very satisfying buy at the right price.

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.
