Bryston 2B SST2 Pro Stereo Amplifier

Next Generation of 2B Power...
The first 2B started life way back in 1979 and has become a Classic among discriminating audiophiles worldwide. This latest version of our 2B incorporates all the new SST2 circuitry and provides twice the power of our original 2B.

From input to output, all the circuitry in the 2B SST2 amplifier has been optimized for the most accurate performance possible. The Bryston 2B SST2 amplifier is a compact, high quality 100 watt per channel, (8 ohms), stereo amplifier intended for use in home sound systems requiring a musically accurate, extremely reliable, no compromise power source.

While the 2B has for years been thought of as an exceptionally lucid and transparent amplifier for traditional two-channel stereo setups, it is now finding additional acceptance in such installations as multimedia surround-sound systems, and in the most ambitious music systems with multi-amplified speakers using electronic crossovers.


Modular design and separate power supplies for each channel ensure cross-talk is essentially nonexistent, and provide precise and focused soundstaging. Components mount directly into glass-epoxy circuit boards, eliminating variations in signal travel and wire interaction. Reviewers agree: sound quality is improved to a stunning degree, realizing a higher, and far more consistent standard of musical accuracy across a line of amplifiers than ever before possible.
