Product Description
The new Bryston B1-200 Cubed ‘2.0’ Integrated amplifier celebrates Bryston’s 50 year and signals a meaningful evolution of the current platform rather than the launch of an entirely new product family.
In this case, the core identity of the Bi-200 remains intact: the design philosophy, intended customer, model position, and overall series architecture continue from the existing generation. However, the changes are substantial enough that the product should not be presented as a minor running update or silent revision.
Together, these updates make the Bryston Bi-200 Cubed ‘2.0’ a more adaptable evolution of the Bryston amplifier platform: evolutionary not revolutionary.
Bryston integrated amplifiers give no ground to their separate counterparts. The new Bi-200 is literally constructed from the Bryston BP-19 Preamplifier and 3B amplifier into a single chassis offering the best of both products without occupying extra space and costly interconnects. High performance and transparency is always our goal, and an integrated amplifier doesn’t have to compromise ability for convenience.
BRYSTON Bi-200 ANALOG CIRCUITS
The Bi-200 analog integrated amplifier is a byproduct of years of R&D that resulted in the development of an optimized discrete buffer amplifier capable of delivering a staggeringly low THD+N distortion.
The analog signal path is a fully balanced design, using an array of very tightly matched components and a compact circuit design to achieve the lowest possible noise and superior common mode rejection. With the new balanced inputs and outputs we have been able to make significant improvements in performance in the Bi-200 Cubed ‘2.0’.
In the past, a fully balanced signal path was difficult to achieve because you would need a volume pot with 4 tapers. With the availability of these new volume control chips, this is no longer an issue. This new design allows for a lower noise floor than previous designs and is much better at common mode noise suppression.
Most Moving-Magnet phono stages expect to receive a signal between 3-6 mV at their input from the cartridge.
The Bryston Moving Magnet stage is a 41dB @1kHz gain preamp with a very unique RIAA playback equalization for moving magnet cartridges.
A step-up Moving-Coil transformer is designed to accept the lower voltage output from the MC cartridge and increase the voltage to a point which is acceptable to the input stage of the standard MM phono section.
The internal proprietary Bryston Moving-Coil step-up transformer in the Bi-200 preamplifier is available in two versions…with a 20dB or a 26dB gain option.
Your choice on which unit is most appropriate will be determined by the voltage output of your chosen cartridge.
From .1 to .2 mV we would recommend the 26dB version.
At .3 mV we would say either version would work fine.
From .4 to .5 mV or more we would recommend the 20dB version An important point to consider when choosing which Step-up to use is you do not want to over-power or under-power the MM phono stage. Under-powering results in not having enough GAIN in the system and over-powering can result in voltage overload and
the resultant distortion.
Moving Magnet: is a 41dB @1kHz gain preamp with RIAA playback equalization for moving magnet cartridges.
Moving-Coil Transformers: 20dB or 26dB inserted before the MM stage.
