Bryston 7B Cubed Mono Amplifier Pair

Meet the 7B Cubed Mono Amplifier Pair

Even the slightest nuance resonates with sparkling clarity.

7B³ mono amplifiers are truly special. Though they don't look much different, they're a big step up from the venerable 4B³. The power supply for this amplifier is built around a specially wound transformer that is substantially more efficient than normal. With twice the power available, they can drive all but the most brutal loads to lifelike levels. But even at whisper-quiet levels, they reveal detail and nuance in your recordings that you never knew existed until now. 

Brystons Cube Series

At Bryston, finding ways to eliminate distortion from their designs is a way of life. All Cubed Series electronics feature a new patented input circircuit that is preciselytimised and linear beyond any they’ve used before. Featuring 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 per cent! Newly designed circuitry in the Cubed Series amplifiers is virtually impervious to noise such as RFI and others induced by external and environmental causes. Bryston's patented Salomie Circuit features a unique method of trapping distortion components in the main signal path that pass through other amplifiers only to be amplified and played by your loudspeakers. This innovative distortion reduction method results in a much more natural and nuanced rendition of your recordings—playback is more true to the original recordings and more enjoyable to your ears. 

Quad-complementary topology improves linearity to a new standard of accuracy while virtually eliminating aggressive higher harmonic distortion byproducts. 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 a separate transformer, a feature uncommon even in amplifiers far more expensive. 

Bryston engineers 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.
