"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."
At the heart of the AMP 20 is its 12-channel Class D amplification, delivering up to 200 watts per channel. This design allows you to drive a full Dolby Atmos or DTS:X setup with ease, without needing multiple amps. Each channel has enough headroom to handle dynamic movie soundtracks, thunderous explosions and subtle musical textures alike. The result is an even, powerful performance across your entire room, ensuring every listener gets the same high-impact experience, whether front and centre or off to the side.
The AMP 20 uses Marantz’s custom Class D amplification modules, engineered for both power and precision. These modules deliver high output without compromising on clarity, letting you enjoy intense soundscapes without distortion. Class D technology is also energy-efficient, so the amplifier runs cooler and is more reliable over long sessions. Whether you're watching a high-action film or listening to a delicate orchestral piece, this amplifier delivers clean, responsive audio that adapts beautifully to your content.
Marantz’s HDAM-SA2 technology is key to the AMP 20’s musical character. These discrete amplifier modules replace traditional op-amps to offer better signal accuracy and lower noise. That means more detail in dialogue, richer textures in music and a more lifelike soundstage. This circuitry helps preserve the emotional impact of every scene or song, making the AMP 20 ideal not just for cinema fans but also for those who love listening to music in high fidelity.
Flexibility is built into the AMP 20 through its selectable output modes. Whether you're using it to drive a full 12-speaker surround system or bi-amping a smaller setup for better performance, you can configure the amp to suit your room and needs. These modes also make it easy to integrate with other components, including the Marantz AV 20, for a fully optimised system. You can grow your setup over time or fine-tune it for specific uses like a dedicated cinema zone or multi-room audio.
The AMP 20 is built in Shirakawa, Japan, where Marantz’s most advanced models are produced. This location is known for precision manufacturing and careful quality control. Each unit is tuned by sound masters to meet Marantz’s exacting standards, ensuring consistent performance across every unit. This focus on craftsmanship means the AMP 20 not only sounds excellent but is also built to last, making it a long-term investment for those serious about their home audio setup.
When matched with the Marantz AV 20 processor, the AMP 20 becomes part of a reference-level home theatre system. The two units are designed to work together seamlessly, offering tight synchronisation and audio performance tailored for cinematic experiences. You get a clean signal path, balanced dynamics and support for the latest immersive audio formats. If you’re building or upgrading a dedicated theatre room, this pairing ensures you’re starting from a point of both power and precision.
