Description

The Marantz Model 10 is the brand’s absolute flagship reference integrated stereo amplifier, representing the most powerful single-box amplification system in Marantz history. It utilizes a newly engineered, fully balanced dual-mono symmetrical topology co-developed with Purifi Audio. Built by hand at the legendary Shirakawa Audio Works in Japan, it features a 1.5cm thick, copper-plated triple-layer chassis designed to systematically isolate low-power sensitive circuits from high-power stages. 

Key Features

    • Marantz & Purifi Audio Platform: Leverages advanced, custom Eigentakt Class-D switching technology built in-house for ultra-low distortion and an exceptionally wide dynamic range. 
    • Three Independent Power Supplies: Features twin custom Marantz SMPS switch-mode power supplies (one dedicated to each audio channel) alongside a separate, third linear supply tasked strictly with powering the control circuitry. 
    • Next-Gen HDAM-SA3 Circuitry: Employs the latest iteration of Marantz’s discrete Hyper Dynamic Amplifier Modules paired with Current Feedback topology for highly musical, detailed transient response.
    • Ultra-Premium Volume Control: Uses a high-performance MUSES 72323 integrated circuit to maintain absolute signal transparency across all gain adjustments.
    • Premium MM/MC Phono Stage: Features completely separate left and right equalizer boards housed inside a copper-anodized aluminum shield case with customizable cartridge impedance matching.
    • Porthole TFT Display: Features Marantz’s classic circular window fitted with a high-definition color screen that can instantly toggle between status indicators or dynamic, digital VU level meters.

Applications

    • Flagship Stereo Listening Rooms: Acts as the high-fidelity power anchor for premium, uncompromising, ultra-high-end audiophile sound systems.
    • Difficult-to-Drive Loudspeakers: Easily tames complex, low-efficiency speaker loads and electrostatic panels down to 2 ohms due to its high damping factor and massive raw current output.
    • Preamplifier Bypass Integration: Includes a dedicated “Power Amp” input mode, allowing it to seamlessly function as a standalone stereo power amplifier within a larger premium home theater setup.
    • High-End Reference Headphone Listening: Incorporates a dedicated, fully discrete headphone amplifier stage pushing 130 mW into 32 Ω with a standard 1/4″ front jack. [1, 2, 3, 4, 5]
