Hegel H20 Stereo Power Amplifier
Overview
The Hegel H20 is a stereo power amplifier built around the latest version of Hegel's FET technology, delivering more than 200 watts per channel into 8 ohms. Its core design is based on Hegel's H30 reference amplifier, using the best possible implementation of Hegel's patented, laser-trimmed SoundEngine modules to deliver a rhythmic, detailed, and natural sound.
Simcoe Audio Video Insight
The FET technology at the heart of the H20 is particularly good at recreating a tight, accurate bass line while removing harmonic echoes in the higher frequencies, so you get more detail without the sound turning harsh. With a damping factor over 1000 and power delivery well over 130 amperes, it maintains full control over demanding loudspeakers. The bead-blasted, anodized aluminum front panel alone contains more than 1.5kg of aluminum, giving it the same rigid, timeless Hegel look as the rest of the lineup.
Best for the Hegel H20: pair it with a dedicated preamplifier like the Hegel P30A or P20 for volume control and source selection, since the H20 is a power amplifier only with no onboard controls beyond a single front power button.

Why the Hegel H20 Stands Out
Over 200W Per Channel, Dual Mono Design
Delivers more than 200 watts per channel into 8 ohms with power capabilities exceeding 130 amperes.
Hegel FET Technology
Delivers a more rhythmic, accurate bass response while removing harmonic echoes in the higher frequencies.
Damping Factor Over 1000
Among the highest in the industry, giving full control over demanding loudspeakers.
Laser-Trimmed SoundEngine Modules
The same patented distortion-cancelling technology found in Hegel's reference H30 amplifier, scaled for a two-channel design.
Rigid, Bead-Blasted Aluminum Chassis
A solid bead-blasted, anodized front panel, top, and side covers for a consistent, exclusive look.
Buyer's Guide
Who It's For
- The Separates System Builder: Wants a dedicated stereo power amplifier to pair with a Hegel preamplifier.
- The Detail-Focused Listener: Wants Hegel's FET technology and SoundEngine distortion correction in a two-channel design.
- The Demanding Speaker Owner: Needs a high damping factor and strong current delivery to control difficult speaker loads.
How It Compares
If you need mono-block power or want to drive extremely demanding speaker loads, the Hegel H30A steps up to over 1100 watts in mono configuration.
