The H30A is an absolute powerhouse of an amplifier. It is both a stereo amplifier as well as a mono amplifier. You choose by a simple rearrangement of input and output cabling. In its mono state it delivers a truly astounding 1100 watts mono mode, 600 wpc Stereo 4 ohms and 300 wpc stereo 8 ohms and it is completely stable even with 1-ohm loads. The H30A power supply uses 2 separate 1000 VA toroidal transformers for fast response and minimized transformer hum. With a power bank of 270,000 μF capacitors, the H30A can handle even the most challenging piece of music at any volume. The output stage uses 56 pieces 15A 200W high speed, ultra-low distortion bipolar transistors. With the H30A you can confidently drive any speaker you like.

Power is however nothing without the details to match. In the H30A input stage, harmonic distortion is eliminated by using single pair FET transistors. These are carefully hand matched transistors that have the exact same values, and therefore they have no higher order harmonic distortion. Other types of distortion is canceled with the patented SoundEngine2 technology. This actively monitors the music signal for corruptions and corrects for distortion using a feed forward design. SoundEngine2 effectively removes distortion in real time as the signal is amplified. These measures make the H30A sound very smooth and natural, without compromising on the details.

The H30A is designed as a mono power amplifier, but it can also be used as a stereo power amplifier. It has both balanced (XLR) and unbalanced (RCA) inputs and a 12V trigger input. The H30A features high quality, gold-plated speaker binding posts. In the H30A the bass is tremendously deep, but never dominating. The high frequencies are exceptionally detailed, but never fatiguing. And the articulation of vocals in the midrange is just sublime. At this level, what you experience is simply total control. The H30A is an amplifier that can drive virtually all known loudspeakers with authority and ease.
