Bryston LTD has introduced the BP17, a state-of-the-art analog/digital stereo preamplifier derived from the preamp portion of the B-135 integrated amplifier.
Basing a component preamplifier design on existing architecture enables Bryston to deliver high performance and build quality at an affordable price, the company says. The BP17 will be available in December, 2012 with an MSRP of $3550.
The BP17 employs Bryston’s most advanced analog circuitry, power supply design and isolation techniques. 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.
The BP17 utilizes a software controlled motorized analog volume dial and integrated balance control, enabling the preamp to be operated remotely while still adhering to fully discrete analog circuits, delivering channel balance and near zero noise or distortion levels, according to Bryston.
“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,” explained 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.”
The Bryston BP17 can be ordered in four configurations—in its standard form, with an optional moving magnet phono stage, with a high resolution internal DAC (Digital to Analog Converter) or fully loaded with both the DAC and phono stage. The BP17 includes provisions for 6 stereo RCA inputs (4 with DAC option), 1 stereo RCA output, 1 stereo tape loop and a headphone output. The Bryston BR2 remote, made from a machined aluminum block, is available as an option.
