Black Hydra HBA-4.130 is focused on uncompromising SQ-audio systems, it is an alloy of honed to perfection technical solutions in the designing of AB-class circuit boards with application of the highest-level components. The model has a completely symmetrical layout and consists of two dual-channel amplifiers in a single body, with separated power supplies.

The amplifier works with increased quiescent currents of the output stages, which, in fact, transfers it into an A c...

Black Hydra HDA-4.90 will appeal to a wide range of car audio enthusiasts who pay special attention to the sound quality of their system. Slightly less than HGA-4.100's output power allowed to make the amplifier more affordable while maintaining the general nature of the sound. But even with this amplifier has an impressive power reserve. Like the top rulers models of the Black Hydra, it is able to stable work at 1-ohm load and allows a bridge connection of subwoofers with...

Black Hydra HGA-4.100 is a real High End, but in a more affordable budget than the Top-End series. The amplifier is built on traditional circuit board solutions of the AB-class. By careful selection of components we have managed to achieve an amazing combination of lightness and high detailing of sound playback with warmth and naturalness of the sound feed.

The dual power supply provides to the amplifier huge power reserve, with which the HGA-4.100 has excellent linearity...
