Bryston 7B³ Mono Block Power Amplifier - EACH

Description Features Specifications The Bryston 7B³ is a single channel (mono) amplifier which offers virtually perfect freedom from overload on any type of speaker. It assures an amazing degree of transparency, musicality, and ease of listening. BRYSTON CUBED SERIES AMPLIFIERS As a result of relentless passion for superb performance and unparalleled build quality, Bryston engineers have continued to innovate since 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, move the listener ever so close to the music with such visceral realism, the experience is most comparable to live performance. 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 Update dress panel aesthetic with clean lines and new finish. Extreme Clarity and Detail 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 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. 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. 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. All Bryston products are proven on our 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. 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. OPTIONS: All amplifiers are available in either C-Series or PRO versions. C-Series models are available in black or silver colored panels and 17 or 19 inches wide. Nineteen inch wide models include front mounted handles (add 1.6 inches to listed depth). PRO models are always black and include rack mountable 19 inch wide panels plus front mounted handles (add 1.8 inches to listed depth).
