Bryston ST Series Amplifiers
Bryston has a continuing commitment to
design and manufacture the most accurate and reliable audio product
available. We maintain an extensive research and development division
which is constantly looking for methods to improve the performance,
value and reliability of out amplifiers. The Bryston ST Series of
amplifiers is the direct result of this continuing quest for perfection.
These amplifiers represent a substantial step forward in the art
and science of audio amplification.
The Bryston ST Series amplifiers incorporate
the use of an innovative gain stage topology which yields a substantially
lower noise floor through the use of low-impedance pathways within
the amplifier. This same approach also has strong advantages in
reducing the overall distortion performance. Bryston’s computer
controlled distortion analyzers confirm Inter-modulation Distortion
levels less than 10 parts per million (below 0.0009%) are typical
for this new circuitry. All ST amplifiers use Bryston’s proprietary
Quad-Complementary output section, which improves linearity to a
new standard of accuracy, while virtually eliminating aggressive
higher harmonic distortion products. From input to output, all the
circuitry in the ST series of amps has been optimized for the most
accurate performance possible. Custom dual torodial power supplies
provide precise and focused soundstaging. The dual power supplies
employ multiple filter capacitors per channel, rather than single
pairs of larger filter cans. This allows improved high frequency
response and reduces overall losses in the supply. Standard features
included both balanced and unbalanced gold plated inputs, a ground
lift switch to reduce those annoying ground loops and a stereo/mono
switch for bridging the outputs if higher power levels are required.
Amplifiers range in power from the 3B ST stereo
unit at 120 watts per channel through the 4B ST stereo amplifier
at 250 watts per channel, to the monstrous 7B ST monaural amplifier
at 500 watts and the multi-channel 120 watt 8B ST. The 3B ST stereo
amplifier at 120 watts per channel provides all the quality and
value of our larger amplifiers but in a package which is both compact
and powerful. Suitable for a wide range of audio/video systems where
sonic accuracy, medium power and long term reliability is required.
The Bryston 4B is something of a legend among
audio amplifiers. As our most popular amplifier over the years,
it has attained inter-national status as an amplifier suitable for
the finest and most sophisticated sound systems. Whatever the venue,
be it a recording studio, a sound stage, a broadcast facility, a
home theater installation, or a state-of-the-art stereo system,
Bryston has continued to be the number one choice.
A unique feature of the 7B ST is a switch allowing
the output stage to operate in a parallel (current) or series (voltage)
mode. This gives the 7B ST the power to drive, with breath-taking
ease and clarity, speakers which have been considered “impossible”
loads in the past.
With today’s interest in home theater, media
rooms and multi-channel music systems, Bryston’s 8B ST provides
switchable operation with four discrete channels at (120 watts),
three channels (one at 400 watts and two at 120 watts) or two channels
at (400 watts). This provides you with an extremely
versatile and flexible amplifier for integrating audio/video systems
requiring multiple channels of amplification.
Although the description of circuit innovations
can indicate the research and commitment we bring to the design
and manufacturing of our audio products, only in the listening does
the result of that dedication become clear. Bryston’s ST Series
amplifiers are capable of doing justice to the most refined audio/video
system, with the subtlest details of the musical fabric revealed
in their original form.
