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 - with detailed transmission of subtle nuances it easily works at elevated levels without showing any signs of signal compression. The sound remains light and dynamic at any volume.

Special attention is paid to the layout of the amplifier’s internal space. Separation of individual parts of the circuit board into sub-boards has reduced and optimized the length of the conductors, which completely eliminates the mutual influence between the channels. The dispersion of the output transistors of the output cascades along the plane of the amplifiers body and their maximum distance from the power unit keys increased the efficiency of heat dissipation and overall temperature stability of the amplifier as a whole.

Black Hydra HGA-4.100 is an excellent choice for enthusiasts who want to build a stereo system with the highest sound quality, including for participation in the SQ categories of auto-sound competitions.
