Ground Zero GZHA mini ONE 750W 1-channel mini amplifier

Hydrogen MINI amplifiers represent the latest class D technology, which is used e.g. in Premium OEM amplifier solutions for new cars.
The difference to the standard D-class is that the sound quality is significantly better in all areas.
You can't tell if it's a high-quality class AB amplifier or a Hydrogen MINI amplifier when listening blindly.
