Add To Cart

Featuring a massive 2 KVA toroidal power transformer and a total of 300,000uF of filter capacitance, the Five-Zero-Zero is designed to accurately reproduce any program material without introducing clipping or distortion.

The Five-Zero-Zero Supreme features an additional MOSFET pre-driver stage, to tightly control the main Dual Die MOSFET output stage - further optimising sonic performance. In addition, high-powered solid state output relays are featured for silent power cycling and lightning-fast loudspeaker protection.

The power output stage remains unconditionally stable, with both channels capable of delivering up to 800 watts per channel continuously into 2 ohm loads.
