Description
The Hegel H30A cannot be easily described. The device feels thoughtful and powerful, with a clear attention to detail. What stands out is the control and finesse with which it does its job. It sounds like everything falls into place without being too present. For those looking for a serious level, this is worth consideration. It is not everyone’s friend, but those who invest in it get something special in return.
The price includes VAT. Entrepreneurs, take advantage of it.
In mono mode, this power amplifier delivers more than 1100 watts at 8 ohms and remains stable at loads up to 1 ohm. The unit can also be used in stereo mode. It features both balanced (XLR) and unbalanced (RCA) inputs, as well as a 12V trigger input. High-quality, gold-plated speaker terminals are provided for optimal connectivity. The power supply consists of two separate 1000 VA transformers and a 270,000 μF capacitor bank, ensuring adequate power and minimal distortion. In the output stage, 56 15-A and 200-W bipolar transistors are used. The input stage uses carefully matched FET transistors to eliminate higher harmonic distortion. In addition, SoundEngine technology is used to correct distortion in real time. The frequency range is wide and the signal-to-noise ratio exceeds 100 dB. The attenuation factor is higher than 500, contributing to a controlled and natural sound’.
Hegel was founded in Norway in the late 1980s by Bent Holter. In his graduate project at Trondheim University of Technology, he developed a solution for reducing distortion in transistor amplifiers. This led to the technology that later became known as SoundEngine. In 1988, the name Hegel was first used for an amplifier. The company released several CD players and amplifiers in the 1990s. In 1996, the first fully balanced amplifier was introduced. Around 2004, the brand began developing DA converters. Later products featured networking capabilities to support digital music playback. Hegel exclusively markets its own electronics, developing both the circuit design and the necessary software itself. The company conducts international distribution of its products from Norway.
