All Cubed Series electronics feature a new patented input circuit precisely optimised and linear beyond any they’ve used before.

Quad Complementary eliminates crossover distortion by improving transistor matching and reduces capacitance in the output stage by a factor of four which improves transient response and bandwidth. The overall harmonic distribution of Bryston’s Quad-Complementary output mimics the characteristics of a class-A design but with dramatically lower distortion. Each amplifier channel includes its own fully independent power supply with separate transformer; a feature uncommon even in amplifiers far more expensive. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBryston engineers strive for accuracy and transparency because that is what sounds best.
