BP20/25 SERIES PREAMPLIFIERS
Bryston’s BP20/25 series preamplifiers offer a significant step
of recorded music. Designed inside and out to reflect the
improvements in the entire Bryston line, these preamplifiers are
a perfect match to our new SST series of amplifiers. All aspects
of the signal flow are greatly improved, with lower noise and
distortion figures, and higher overload levels.
FEATURES INCLUDE
Intermodulation distortion has been reduced to less than
.0015% from 20 to 20kHz.
The noise floor has been significantly improved, reducing
background hash to far below audibility.
Input to input crosstalk is essentially nonexistant to eliminate
signal bleed-through from one source to another.
Components plug directly into glass-epoxy circuit boards,
All BP20/25 series preampliers are housed in steel cabinets
for shielding to reduce electromagnetic interference effects.
Buffered inputs provide for lower distortion and improved
linearity from source components. A ground plane has been
incorporated in this new design to further reduce crosstalk
and noise throughout the internal circuitry. The power
transformer is mounted externally to eliminate power-supply
noise interference.
Each and every BP20/25 series amplier is assembled by
hand and burned in for 100 hours to ensure performance for
many years to come. It is backed by a 20 Year Warranty
— unrivaled in the industry.
eliminating variations in signal travel and wire interaction.
Signal switching and audio connections utilize heavy gold
plating to provide long-term trouble-free connections.
Gold plated balanced and unbalanced input and output
connectors are standard.
A 12 volt AC/DC screw terminal connector on the rear of
the power supply provides for a convenient remote start
feature available on all Bryston amplifiers.

MM/MC PHONO SECTION
The huge library of music present
on vinyl represents an irreplaceable
treasure. As such it becomes more important than ever to
reproduce the music with the greatest faithfulness to the
original recording.
The new BP20/25 DA preamplifier provides a digital interface
using premium quality digital to analogue converters on 2
switchable stereo SPDIF inputs (RCA) and Bryston’s fully discrete
Class A operational preamplifier sections.
This digital to analog option provides a state of the art upgrade
path for customers wanting to improve the digital capability of
their stereo CD or DVD players. Simply plug the digital out from
your CD/DVD player into the Bryston BP20/25 DA. The quality
of sound using fully discrete Class A operational amplifiers,
rather than the typical IC’s, has to be heard to be believed.
Brystons unique and innovative Phono Section is available as
an optional built in feature in either moving magnet (BP20/25P)
and/or moving coil (BP20/25MC) version. It offers a broadcast
quality uncomplicated package for those who enjoy the ultimate
in vinyl playback.
Our feeling is that Bryston’s BP20/25 series preamplifiers are
one of those fortunate circumstances when the long hours and
extended listening pays off. The sense of transcending the
recording medium and experiencing the original performance
is captured with exceptional realism. We invite you to
audition one today.
