Hegel H20 Stereo Power Amplifier
Overview
The Hegel H20 is a dual mono stereo power amplifier that delivers more than 200 watts per channel into 8 ohms. Its core design comes from Hegel's H30 reference amplifier and uses the best implementation of Hegel's patented, laser-trimmed SoundEngine modules. It's for listeners building a separates system who want serious power and control for their loudspeakers, paired with a preamplifier of their choice.
The H20 uses the latest version of Hegel's FET technology. In practice, that means a more rhythmic sound that's better at recreating a bass line, and the removal of harmonic echoes in the higher frequencies for more detail with a smoother, more natural top end. Power capabilities exceed 130 amperes, distortion is extremely low, and the damping factor of more than 1000 is among the highest in the industry, so the H20 keeps full control of the speakers.
Power comes from a 1000 VA dual mono supply with 90,000 μF of capacitors, feeding an output stage of 20 high-speed, ultra-low-distortion bipolar transistors. The front has just one button on a bead-blasted, anodized aluminium panel, with well over 1.5 kg of aluminium in the front panel alone, and the top and side covers are bead-blasted and anodized to match.
Simcoe Audio Video Insight
The H20 is a power amplifier only, with a single power button on the front, so it needs a preamplifier for volume and source selection. A Hegel preamplifier such as the P20 is a natural match, though any quality preamp or integrated amplifier with preamp outputs will work. Use the balanced XLR input when your preamp offers it.

Buyer's Guide
Who It's For
- The Separates Builder: Wants a dedicated stereo power amplifier.
- The Demanding Speaker Owner: Needs high current and tight control.
- The Detail-Focused Listener: Wants low distortion and natural sound.
How It Compares
The H20 is built on the design of Hegel's H30 reference amplifier but in a two-channel, single-chassis package. Compared with an integrated amplifier, separating the power amplifier from the preamp gives the H20 its own dedicated dual mono power supply and output stage.
