In this Marantz AV20 Reference AV Preamplifier Review, we dive into why the AV20 sets the benchmark for reference-level home theatre. Combining Marantz’s iconic HDAM discrete circuitry and a copper-plated chassis with a toroidal power transformer, the AV20 is crafted to deliver pin-sharp dynamics, pristine imaging and effortless control of even the most demanding multichannel formats.

Design & Build Quality

From the moment you place the AV20 on your rack, its metal front panel and minimalist aesthetic exude confidence. The copper-plated chassis and heavy-duty toroidal transformer minimise resonance and interference, ensuring a rock-solid foundation for your system. Thoughtfully laid-out controls and a two-line FLD display make setup a breeze, while the modern HD GUI guides you step by step.

Performance & Sound Signature

At the heart of the AV20 is Marantz’s Current Feedback topology and monolithic Hyper Dynamic Amplifier Modules (HDAM-SA3), fine-tuned by Sound Master for reference accuracy. Whether you’re listening to a 13.4-channel Dolby Atmos mix or a two-channel hi-res FLAC recording, the AV20 delivers authoritative bass, transparent midrange and an airy top end. Dynamics are explosive yet controlled, and soundstaging is impressively three-dimensional. IMAX Enhanced, Auro-3D and 360 Reality Audio support elevate every soundtrack with immersive height channels and precision placement.

Connectivity & Feature Set

The AV20 is endlessly customisable. Seven HDMI 2.1 inputs (8K/60Hz, 4K/120Hz) with HDCP 2.3, eARC and full HDR support (Dolby Vision, HDR10+, HLG, Dynamic HDR) cover all sources. Variable Refresh Rate, Auto Low Latency Mode and Quick Frame Transport make it a gaming powerhouse. Analogue lovers will appreciate six RCA inputs (including XLR), a Phono MM stage and four independent subwoofer outputs. Audyssey MultEQ XT32 room correction is onboard, with optional Dirac Live upgrade for integrators seeking surgical acoustic tuning.

Stream seamlessly via HEOS® Built-in, with access to TIDAL, Amazon Music HD, Spotify and more. Roon-Ready, AirPlay 2 and Bluetooth retransmit provide flexible options for every listening scenario.

Who Should Consider the Marantz AV20?

If you’re a cinephile chasing reference-grade dynamics, an audiophile wanting lossless multi-room streaming or a custom installer needing robust digital I/O and calibration tools, the AV20 is tailored to your needs. Its feature-rich platform grows with your system—pair it with a matching AMP20 monoblock for even greater control and headroom.
