Bryston 4B3 Amplifier

Bryston 4B3 Amplifier

The Bryston 4B3 Amplifier is available for demonstration in our Hull store.

The Bryston 4B³ amplifier is a stereo power amplifier which is acclaimed internationally as being suited for the finest and most sophisticated sound systems. The Bryston 4B3 is currently the most popular Cubed Series model.

At Bryston, finding ways to eliminate distortion from their designs is a way of life. The Bryston 4B3 Amplifier features a new patented input circuit that is precisely optimized and linear beyond any we’ve used before.

The Bryston 4B3 amplifier features twelve active devices in a groundbreaking array, this new circuit both matches the amplifier to virtually any preamplifier and provides the first 6dB of gain. The new input stage is so transparent, its measurable distortion is less than 1/1000th of 1 percent.

Newly designed circuitry in the Bryston 4B3 Amplifier is virtually impervious to noise such as RFI and others induced by external and environmental causes.

The Quad-Complementary topology improves linearity to a new standard of accuracy while virtually eliminating aggressive higher harmonic distortion byproducts. The overall harmonic distribution of Bryston’s Quad-Complementary output mimics the characteristics of a class-A design but with dramatically lower distortion. Each Bryston 4B3 Amplifier channel includes its own fully independent power supply with separate transformer.

Bryston strive for accuracy and transparency because that is what sounds best. When a playback system is faithful to the recording, the listener can enjoy the most subtle details, capturing the depth and soul of the performance as the artist intended.
