The Hegel H20 is a dual mono stereo power amplifier from Norway, delivering over 200 watts per channel into 8 ohms with peak current capability above 130 amps. Its core design is based on the Hegel H30 reference amplifier, using the latest version of Hegel's FET technology with laser-trimmed SoundEngine modules in the most precise implementation Hegel offers at this price. ProHiFi is an authorised Hegel dealer in India.
The dual mono power supply uses a 1,000 VA transformer with 90,000 microfarads of capacitance, and the output stage uses 20 high-speed, ultra-low distortion bipolar transistors per channel at 15A/200W each. The damping factor exceeds 1,000, providing exceptional speaker control across the full audio bandwidth. Distortion is below 0.006% at 100 watts into 8 ohms.
Balanced XLR and unbalanced RCA inputs are provided for each channel, with two pairs of heavy-duty gold-plated speaker terminals per channel for bi-wiring. The chassis uses a bead-blasted and anodised front panel with over 1.5kg of aluminium, and bead-blasted anodised top and side covers for a consistent finish throughout. A single button on the front panel keeps the visual design uncluttered.
SoundStage Hi-Fi called the H20 as highly recommended as almost anything else they had ever reviewed, noting it competed head-to-head with amplifiers costing several times the price. Reviews from Audio Basic Japan, Stereo Sound Japan, Haute Fidelite France, Hifi and Musik Sweden, and StereoLife confirm the H20's standing as an exceptional value proposition at its price.

Why Consider the Hegel H20
The H20 is the right choice for listeners who want to add a high-current, high-damping-factor stereo power amplifier to a Hegel or third-party preamplifier, or to upgrade from the power stage of an integrated amplifier using its pre-out. The 130 amp peak current capability and 1,000+ damping factor give it the ability to control demanding speaker loads that lower-powered amplifiers struggle with, and the dual mono construction gives each channel a fully independent power path. SoundStage Hi-Fi's conclusion that it competes with amplifiers at several times the price has been echoed by reviewers in Japan, France, and Sweden. Paired with the Hegel P20 or P30A preamplifier, it forms a complete Hegel separates system with natural tonal balance, authoritative bass, and smooth high-frequency reproduction.
Ideal for
- Listeners upgrading the power stage from a preamplifier or integrated amplifier pre-out
- Systems pairing with the Hegel P20 or P30A preamplifier as a matched Hegel separates pair
- Demanding speaker loads requiring 130A peak current and 200W sustained output
- Bi-wiring configurations using the dual speaker terminal pairs per channel
- Those who want Hegel's SoundEngine distortion correction in a dedicated power amplifier
