Hegel H30A Power Amplifier
Overview
The Hegel H30A is Hegel's reference power amplifier, nicknamed The Orchestra. Designed as a mono amplifier, it delivers more than 1100 watts into 8 ohms and stays completely stable even with 1-ohm loads, so speaker sensitivity and difficult impedance curves stop being a concern. It can also be used as a stereo power amplifier. It's for listeners building a reference system who want an amplifier that can drive virtually any loudspeaker with authority and ease.
The power supply uses two separate 1000 VA toroidal transformers for fast response and minimal transformer hum, backed by 270,000 μF of capacitors so there's always power in reserve, even for large orchestral pieces at high volume. The output stage uses 56 high-speed, ultra-low-distortion bipolar transistors rated at 15 A and 200 W each.
Power means little without detail, so the input stage uses hand-matched single-pair FET transistors with identical values to eliminate higher-order harmonic distortion, the kind that makes amplifiers sound harsh. Hegel's patented SoundEngine then monitors the signal and cancels other distortion in real time with a feed-forward design. The result is deep bass that never dominates, detailed highs that never tire and a relaxed, natural sound.
Simcoe Audio Video Insight
The H30A is designed as a mono amplifier first, so a pair, one per speaker, driven from a preamplifier such as the Hegel P20 makes the most of it. The 12 V trigger input lets both amplifiers power on with the preamp. At 47.4 kg each, plan for a sturdy, well-ventilated shelf or amp stand, and use the balanced XLR inputs when your preamp has them.

Buyer's Guide
Who It's For
- The Reference System Builder: Wants Hegel's flagship power amplifier.
- The Demanding Speaker Owner: Needs stability into very low impedances.
- The Mono Block Enthusiast: Wants a dedicated amplifier for each speaker.
How It Compares
Compared with Hegel's H20 stereo power amplifier, which delivers more than 200 watts per channel, the H30A is a mono-first design with more than 1100 watts into 8 ohms, a 2000 VA power supply and stability down to 1 ohm, built for the most demanding speakers and largest rooms.
