Full Description
AV Forums Editors Choice – Best High-End AV Processor 2025/2026
"Marantz has just made life a little easier for those with not quite as deep pockets as customers of the flagship AV 10 and AMP 10. This latest '20' package consisting of both AV processor and power amplifier still sounds marvellous."
EISA Premium AV Preamplifier 2026-2027
"With features including HEOS music streaming, MM phono input, a built-in headphone amp and multi-zone operation, there’s almost nothing Marantz’s AV preamplifier can’t do."
Reference-Quality Sound
At the heart of the AV 20 is a 13.4-channel configuration, giving you the tools to craft an immersive surround sound setup. Whether you're using overhead speakers for Dolby Atmos or expanding your layout with height channels, this preamp ensures accurate placement of every sound. The result is a surround experience where you can feel every detail, from subtle footsteps to thundering explosions, delivered with cinematic clarity and scale.
HDAM Discrete Circuitry
Marantz's proprietary HDAM (Hyper Dynamic Amplifier Module) circuitry replaces standard op-amps with precision-tuned discrete components. This design reduces noise and distortion, so you get a more dynamic and detailed soundstage. The AV 20 benefits from this by maintaining clarity across all frequencies, giving vocals natural presence and instruments more lifelike texture – even at high volumes or during complex scenes.
Future-Proof 8K HDMI Connectivity
All seven HDMI inputs on the AV 20 support 8K UHD, ensuring you’re ready for the latest video standards and content. This means crystal-clear visuals, sharper detail, and smoother motion on compatible displays. Enhanced features like eARC (enhanced Audio Return Channel) and support for HDR formats such as Dolby Vision ensure seamless integration with next-generation gaming consoles, Blu-ray players, and streaming devices.
HEOS Built-in for Whole-Home Audio
With HEOS Built-in, the AV 20 connects to a wider ecosystem of wireless Marantz and Denon speakers. You can stream music from services like TIDAL and Amazon Music HD in high resolution and enjoy it in any room of your house. The HEOS app gives you full control, letting you group rooms, manage sources, and search for songs—all from your phone.
Sound Master Tuning for Detail and Depth
The AV 20 has been tuned by Marantz Sound Masters, experts in shaping how every unit sounds. Their goal is to balance clarity, warmth, and emotional impact so that music and movies feel engaging without fatigue. The attention to tuning ensures that dialogue remains crisp, low-end stays tight, and the overall mix maintains its intended dynamic range. .
Customisable System Integration
Whether you’re working with legacy equipment or the latest components, the AV 20 is designed to slot into your setup with ease. Balanced XLR outputs, advanced system calibration options, and multi-room compatibility make it ideal for bespoke installations. Whether you're integrating it with high-end amplifiers or building a full home theatre network, this preamplifier provides the flexibility and control needed to get the best from your system.
