State-of-the-art Analog Stereo Preamplifier
The Bryston BP17 is a state-of-the-art analog stereo preamplifier, utilizing software control which allows Bryston to provide many more features and functions. The BP17 delivers incredible sonic performance while still adhering to traditional, fully discrete, analog circuits throughout the preamplifier. The BP17 offers a dramatic improvement over the BP16 by incorporating much of the existing architecture developed for the Bryston B135 integrated amplifier and SP3 surround sound processor.
The BP17 employs Bryston's most advanced analog circuitry, power supply design, and isolation techniques, providing audio aficionados with an ultimate performance preamplifier that delivers outstanding sonic performance. Much of the technology in the BP17 required over two years in engineering and development resulting in major advances to the analog circuitry derived from the company's SP-3 processor platform.
Near Zero Noise and Distortion Levels
The BP17 utilizes a software controlled motorized analog volume dial and integrated balance control. This approach enables the preamp to be operated remotely while still adhering to fully discrete analog circuits, delivering perfect channel balance and near zero noise and distortion levels.
"We have reduced Total Harmonic Distortion (THD) levels in the BP17 by utilizing buffer amplifiers optimized for wide open-loop bandwidth and low open-loop THD," notes Bryston CEO Chris Russell. "These carefully selected components essentially eliminate the increase in THD with rise in frequency exhibited by almost all op- amps, giving the BP17 phenomenal detail and complete lack of grain in the sound field."
"The BP17 also features a brand new balanced action volume control, eliminating another source of distortion while maintaining channel-to-channel tracking within 1/10dB over the full range of control," Russell said.
The BP17 includes eight stereo RCA inputs, one stereo RCA output, one stereo tape loop, and a headphone output. The Bryston BR2 remote, made from a machined aluminum block, is available as an option.
Bryston applies techniques and employs custom materials in its everyday manufacturing of electronic equipment that are more typically utilized by the military and aerospace industries. Such techniques ensure unit-to-unit consistency that is vastly superior to mass production. Bryston's adherence to the use of proprietary parts, sophisticated construction, and refined testing techniques guarantees superb performance and long-term product reliability.
Bryston's 20-Year Warranty
In a world where most things seem to need frequent upgrading, repair, or replacement, Bryston offers a comprehensive, unconditional, and fully transferable warranty on every audio product its makes. The company's 20-year amplifier warranty and five-year digital circuit warranty drives it in a different direction from the typical manufacturer.
How can Bryston do it? The answer would quickly become apparent if you were to tour Bryston’s plant in Peterborough, Ontario, Canada. State-of-the-art design facilities, with the latest CAD and circuit simulation software, and an inventory of some of the best and most reliable parts on the planet, combine with a manufacturing philosophy that eschews the artifacts of mass production, like robots, moving assembly lines, and, frankly, shortcuts. Every Bryston audio component is handcrafted by people who take great pride in building the very best.
Rigorous Inspection and Testing
Bryston doesn't skimp on testing or rush its products through some last-minute go/no-go check. At every stage individual parts, completed circuit boards, sub-assemblies, and final assemblies are all put through rigorous inspection and testing procedures.
