Flagship true Reference pair of Mono block Power Amplifiers :

The 28B³ is Bryston's flagship power amplifier, a single channel (mono) amplifier which sounds incredibly detailed and musical at very low levels and maintains that same sophistication and drive capability with even the most difficult inefficient speakers, large or small.

The 28B³ boasts one channel capable of 1000 watts intended for use in very high performance professional audio systems. Robust yet beautiful machined aluminum enclosures house a proprietary industry-leading circuit design, resulting in exemplary performance observed both in the listening space and in the laboratory.

The Bryston 28B³ amplifier can receive analog audio from any preamp or surround processor with volume controlled line-level outputs. A balanced XLR input as well as a singled ended RCA input are both available and can be selected using the Input Select switch on the rear panel of the amplifier.

Integrate the 28B³ with other electronics in your system. The low-voltage trigger on the back of the amp can be connected to your Bryston preamp to automatically power on when you turn on your preamp.

Every single 28B³ comes with an individual specification sheet. You'll see exactly how well your particular amplifier performed on the test bench. And like every Bryston amplifier, each 28B³ is tested for 100 hours in the factory before it ships to ensure long term reliability.

Bryston Cubed Series Amplifiers:

Bryston amplifiers enjoy universal acclaim from both audio professionals and music enthusiasts unlike any other brand in the world. As a result of relentless passion for superb performance and unparalleled build quality, Bryston engineers have continued to innovate since the company's groundbreaking premier in 1976. The Cubed Series amplifiers continue this tradition of excellence, highlighted by lower distortion, increased bandwidth, and reduced noise, presenting listeners with a crystal clear window into their most favorite recordings.

Bryston Cubed Series Amplifiers, featuring patented circuitry developed in conjunction with Dr. Alexandru Salomie, move the listener ever so close to the music with such visceral realism, the experience is most comparable to live performance.

What Defines High Performance?

Reproducing exactly what is captured in a recording without exception and without added distortion fulfills Bryston's definition of high performance. Each Bryston Cubed amplifier is designed without compromise in pursuit of this lofty goal.

Bryston engineers, led by Christopher Russell, have been busy over the years since the advent of the SST2 Series finding new methods to reduce noise and distortion to reveal more nuance and subtlety than ever before. Cubed Series amplifiers employ significant improvements over the highly acclaimed SST2 Series, including dramatically less distortion at the input stage, improved common mode noise rejection, a major improvement in EMI/RFI noise rejection, and less than 500mW standby power consumption. Finally, Bryston updated the dress panel aesthetics with clean lines and a new finish.

Extreme Clarity and Detail

At Bryston, finding ways to eliminate distortion from its designs is a way of life. All Cubed Series amplifiers feature a new patented input circuit that is precisely optimized and linear beyond any that Bryston has 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.

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 amplifier channel includes its own fully independent power supply with separate transformer.

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

Legendary Quality :

Cubed Series amplifiers employ design innovation to achieve superior performance, yet so much has remained constant through years of evolution. Each amplifier is manufactured in Bryston's state-of-the-art facility located in Peterborough, Ontario, Canada, utilizing many locally sourced components. Many members of the Bryston team have been with the company for decades and all take great pride in their highly specialized craft.

All Bryston products are proven on the company's test bench for one hundred hours of burn-in before shipping. Amplifiers cycle between full power and idle in thirty-minute intervals to uncover any anomalies that could be illuminated by thermal stress. Bryston's reputation for reliability is without peer.

Not only do Bryston's amplifiers undergo pass/fail testing, but each must also achieve excellence in performance benchmarks as well. With each Cubed Series model, the customer will receive a comprehensive performance certificate detailing the exact specifications of the amplifier.

To demonstrate its commitment to excellence and performance, every Bryston amplifier is warranted to be free of defects in materials and workmanship for a full twenty years.

The music they reproduce is full-sounding, very powerful with a lot of drive, and the music has a weight and a density, with real substance to it. The sound is very warm, musical and natural sounding. It is never harsh, clinical, nor aggressive or irritating." -
