According to Bryston, its 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.”
The new Bryston 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. The BP-173 is available in either black or silver, 17-inch or 19-inch (wide) faceplates.
The BP-173 will begin shipping to authorized dealers in September 2017, with a US MSRP of $3995. The DAC and phono stage options have an MSRP of $750 each. The BR-2 remote has an MSRP of $375. All orders placed for the BP-173 by August 31 will qualify for one optional accessory at no additional cost: internal phono stage, internal DAC or BR-2 remote control.
