Know before you buy
The Hydra combines a tube front end with a Class D output stage to provide the organic, warm harmonic texture of vacuum tubes alongside the high-efficiency power and precise speaker control of solid-state technology.
No. The Hydra is designed for convenience and does not require manual tube biasing or regular maintenance, making it as easy to operate as a standard solid-state amplifier.
Yes. The Hydra is equipped with both balanced (XLR) and single-ended (RCA) inputs, allowing it to integrate seamlessly with a wide variety of preamplifiers and source components.
The amplifier delivers 100 watts per channel into 8-ohm speakers and doubles that to 200 watts per channel into 4-ohm loads, providing plenty of headroom for most high-fidelity speaker systems.
No, the Hydra is a dedicated power amplifier and does not feature an integrated digital-to-analog converter or remote control functionality.
The Hydra is not designed for rack mounting. It is intended to be placed on an open shelf or audio stand with adequate ventilation to accommodate its 18-inch width and 5.5-inch height.
