The Bryston 3B3 is a powerful dual-channel amplifier designed to power medium and large systems without sacrificing accuracy and reliability.

The Bryston 3B3 uses a new patented input circuit to provide highly optimised and linear behaviour. Bryston achieves this through the use of twelve active devices in a groundbreaking array. It allows for the precise matching of any preamplifier as well as providing the first 6dB of gain. The result is a pristine amplification circuit with less than 0.0001% of measured distortion.

Furthermore, the 3B3 uses a Quad-Complementary output for improved linearity and suppression of aggressive higher harmonics distortion. The overall harmonic distribution resembles that of Class A topology but with far less distortion. RFI and Electromagnetic interferences are virtually eliminated from the circuit.

Each channel includes a dedicated power supply with separate transformer.
