The SST2 C–Series is without peer in meeting this performance challenge.
Next Generation of 4B Power...
The Bryston 4B is something of a legend. As our most popular model, it has attained international status as an amplifier suitable for the finest and most sophisticated sound systems. In its latest incarnation, the 4B SST2, it is a dual mono design delivering a massive 300 Watts per channel into 8 Ohms. Whatever the venue, be it recording studio, concert stage, broadcast facility, home theater installation, or state-of-the-art stereo system, the 4B SST2 continues as the number one choice.
The 4B SST2 is a pure dual mono design and offers 300 watts per channel into 8 Ohms, 500 watts into 4 Ohms and over 1000 watts available in bridged mono mode.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.
