Bryston 28B Cubed Mono Amplifier Pair

Presenting the 28B Cubed Mono Amplifier Pair
Even the slightest nuance resonates with sparkling clarity.
Besides the fact that this is one of the most powerful amplifiers on the market and can drive virtually any loudspeaker with total grace and ease, the 28B³ monoblock amplifiers are some of the finest sounding models ever at any power output.

These amplifiers take complete control over your loudspeakers and command them to be their best. Bryston first-to-last-watt philosophy demands that each of their products sounds equally amazing at all power output levels.

There is no product they have ever engineered that demonstrates this philosophy better than the 28B³. Even if you don't need all the power these amps offer, you owe yourself the pleasure of a demonstration. Hear the 28B³ today.

Brystons Cube Series

At Bryston, finding ways to eliminate distortion from of their designs is a way of life. All Cubed Series electronics feature a new patented input circuit precisely optimised and linear beyond any theyve 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 percent! 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 feature 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 recordingsplayback 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 Brystons 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. 

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.
