50 watts of Marantz Class A/B amplification. HDMI ARC. Bluetooth with aptX Adaptive. Built-in MM phono stage. ES Sabre DAC. The Marantz MODEL 70 brings decades of hi-fi heritage and signature musical performance into the modern home — for every ritual, every source, every listen.

Crafted for Musical Experiences That Move You

There are amplifiers that reproduce sound. Then there are amplifiers built around the conviction that music should move you — that every listening session, every ritual, every source deserves to be experienced at its full emotional and sonic potential. The Marantz MODEL 70 belongs firmly in the second category.

Harnessing Marantz's decades-long history of audio excellence, the MODEL 70 brings signature hi-fi heritage and remarkable performance into the modern home. Its generous connectivity — MM phono stage, HDMI ARC, Bluetooth with aptX Adaptive, optical and coaxial digital inputs — ensures every source is elevated. Your vinyl rituals: warm and immersive. Your CDs: dynamic and expressive. Movie night: cinematic and lifelike. Whether listening through your favourite speakers or privately on headphones, the MODEL 70 delivers effortlessly musical performance that you won't soon forget.

Enhanced Clarity and Detail — Refined Amplifier Design

The MODEL 70 features a refined amplifier design built around Current Feedback Topology — a circuit architecture chosen for its exceptional speed, low distortion, and wide bandwidth. Combined with Marantz's HDAM SA3 (Hyper Dynamic Amplifier Module) and a toroidal power transformer with Linear Drive Power Supply, the signal path has been optimised to reduce noise and enhance clarity at every stage.

The result is a more open, more precise sound — one that allows you to hear deeper into every performance. Subtle details that lesser amplifiers obscure emerge naturally and without effort. The music breathes. The soundstage opens. This is what Marantz's Sound Masters have spent decades perfecting.

Genuine Power — 50W, High-Current Class A/B

The MODEL 70 delivers 50 watts per channel into 8 ohms, rising to 65 watts into 4 ohms — with high-current capability for confident, authoritative speaker control across a wide range of loudspeaker loads. Class A/B topology ensures natural, musical amplification character with the efficiency needed for real-world listening. Solid aluminium extrusion heat sinks, Schottky diodes, and solid heat sinks all contribute to a stable, low-distortion operating environment — even at sustained high output levels.

Modern Connectivity — Every Source, Elevated

The MODEL 70 is designed for the way modern listeners actually use their systems. HDMI ARC allows your TV's audio to be routed through the MODEL 70 and its connected speakers — transforming television viewing into a genuinely cinematic experience. Bluetooth with aptX, aptX HD, and aptX Adaptive delivers high-quality wireless audio from smartphones, tablets, and computers. A built-in MM phono stage connects your turntable directly. Optical and coaxial digital inputs, processed through an ES Sabre DAC, handle CD players, streamers, and other digital sources with precision. A pre-amp output with dedicated subwoofer output and Source Direct mode complete a connectivity picture that leaves nothing wanting.

Timeless Marantz Design

The MODEL 70 wears the Marantz design language with quiet confidence — the signature porthole window, low-noise OLED display, and clean front panel aesthetic that has defined Marantz components for generations. Available in Black and Silver-Gold, it is a product that earns its place at the centre of any listening room, as a visual statement as much as a sonic one.
