"The BP-173 is the Bargain Preamplifier to Beat" –Stereophile
Super-Linear, Super Low Noise Line-Stage Preamp
Bryston's long-awaited BP-17³ preamp is the company's first to employ the patented Salomie input circuit along with a brand new feature set. It utilizes patented technology that debuted on Bryston's much heralded Cubed Series amplifiers. The BP-17³ also features a new expanded input/output configuration for enhanced system flexibility. Like all analog components from Bryston, the BP-173 is covered by an industry-best 20-year warranty.
Bryston’s patented super-linear, low noise input buffer jointly developed by Bryston and the late Ph.D. engineer Dr. Ioan Alexandru Salomie significantly reduces noise and distortion. The BP-17³ also has improved RF and audio frequency noise filtering to prevent unwanted anomalies on the power line from interfering even minutely with the audio signal.
"Engaging, Detailed, Tonally Captivating, Utterly Natural Sound"
"Among new, high-value, line-level preamplifiers, the BP-173 is a welcome find," reports Larry Greenhill in his May 22, 2018 review for Stereophile. "Indeed, the BP-173 costs less than any solid-state preamp listed in Class A of the April 2018 edition of 'Recommended Components.'"
"It produced engaging, detailed, tonally captivating, utterly natural sound that approached reference quality," continues Larry Greenhill Stereophile. "Matched with a top-quality, compatible power amplifier, the BP-173 is the bargain preamplifier to beat… Strongly recommended."
"With the 17B3, Bryston has finally produced a pre-amp that is an able and sonically talented match for the marque’s power amplifiers," reports Deon Schoeman in his review for AudioVideo, avsa.co.za. "It has the ability to unlock the essence of the music, and to present it with a compelling sense of realism."
Expanded Input and Output Options
The BP-17³ offers expanded input/output options, including two pairs of XLR outputs and two pairs of RCA outputs, making it possible to connect a wide variety of equipment and accommodate numerous system configurations. An RCA tape loop lets users connect a line-level processor or recording device, and one of the XLR output pairs can be internally selected to have either variable (default) or fixed output, enabling users to easily connect a Bryston BHA-1 or other balanced input headphone amplifier.
The BP-17³ also includes two pairs of balanced inputs and five pair RCA inputs, and can be ordered with a high-resolution internal DAC, a premium moving magnet phono stage, both DAC and phono modules or without either module installed. Users can select sources, adjust volume and more all from the optional BR-2 remote control or via RS232 connection to virtually any control ecosystem.
Ultimate Quality
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.
