The Bryston 14B³ Amplifier provides excellent freedom from overload for your speakers. This dual channel (stereo) amplifier assures excellent listening with its amazing degree of transparency and musicality.

The Bryston 14B³ dual channel (stereo) amplifier is basically two 7Bs which have been combined in a dual mono modular design and has the power to drive with breath-taking ease and clarity, speakers which have been considered "impossible" loads in the past.

"The Bryston amplifier is a bit of a dynamic weapon, along similar lines as other very expensive amplifiers that have graced the listening room."

— Edgar Kramer, Audio Esoterica

The 14B3 is a dual-mono design audio power amplifier with two channels capable of 600 watts each intended for use in very high performance professional audio systems. Robust yet beautiful machined aluminum enclosures house our proprietary industry-leading circuit designs resulting in exemplary performance observed both in the listening space and in the laboratory.

"If you are looking for amplifier honesty and the ability to drive any speaker in the largest of rooms, or just like the power reserve on hand in your modest listening area, this is one to consider."

— John Gatski, Everything Audio Network

First to Last Watt Philosphy

A significant part of the design criteria for the new Cubed series was to develop amplifiers that would maintain an ideal power curve from the first watt to the last. Most amplifiers exhibit a power curve where the best noise floor, drive capability and distortion are acheived from about 1/3 power and up. The new Bryston Cubed series amplifiers maintain their ideal power curve starting right from the first watt.

Achieving this starts with a number of design approaches:

  1. Complete freedom from low-level crossover, zero-crossing, artifacts

    Most class-AB amplifierrs have sufficient bias to prevent primary crossover distortion, but secondary crossover distortion is caused by insufficient speed in the driver transistors. The Cubed Series uses very fast drivers to help prevent this, as well as proprietary technology. Bryston's Quad Complementary Output design vastly reduces the capacitance seen by the driver transistors, virtually eliminating storage delay in the output stage that could contribute to nonlinearities in the zero-crossing region.

  2. Continuing efforts to reduce low-level noise. The clarity of level noise

    The clarity of Bryston's designs is enhanced at low listening levels by pushing the noise floor far below the signal level, improving the silence between the notes and enhancing the clarity of the music at low power levels.

  3. Concentration on reducing distortion at all levels, especially high frequencies

    Bryston amplifiers are perhaps the only designs to concentrate so much effort at reducing HF distortion artifacts, and the results are remarkably flat THD-with-frequency curves, sho frequency curves, sho frequency curves, showing almost no tendency to wing almost no tendency to increase distortion as frequency rises. This has the effect of reducing overall haze, helping to pull the quietest passages out of the background.

Additionally, the new Cubed Series employs highly effective RF employs highly effective RF rejection in the power supplies, which traps and eliminates radio-frequency hash from either interfering with or emanating from the amplifier via the power cable or signal cables.

"It was time to give the Bryston Middle Ts a turn with the 14B³. These proved to be amazing speakers that sound so much larger than one would expect, given their slender footprint. I played all the previous tracks again, as well as others, and I heard just how well the 14B³ controlled the Middle T, displaying deep articulate bass with just the right amount of mid-bass."
