Bryston Cubed Series Amplifiers (report from factory)

What’s New?

Bryston engineers 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 including:  

Dramatically less distortion at input stage.

Improved common mode noise rejection.

Major improvement in EMI/RFI noise rejection.

Less than 500mW standby power consumption.

Updated front panel aesthetic with clean lines and new finish.

Extreme Clarity and Detail

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

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 our 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 take great pride in their highly specialized craft.

All Bryston products are proven on our test bench for one hundred hours of burn-in before final test & shipping.  Amplifiers cycle between full power & idle in thirty minute intervals to uncover any anomalies that could be revealed by thermal stress.  Our reputation for reliability is without peer.

Not only do "our" amplifiers undergo pass/fail testing, but each must 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 our 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 warranty is fully transferable...most manufacturers do not do this.
