About the 9B-SST

The Bryston 9B-SST is a hand-crafted, modular, single-chassis 5-channel power amplifier. Each channel contains all the electronic circuitry, connections, and an independent power supply to deliver high sonic quality. It provides 120 watts per channel into 8 Ohms and 200 watts per channel into 4 Ohms. The amplifier features a robust pro audio construction with a quad-complementary output stage and multiple filter capacitance per channel. It has a damping factor of 500, total harmonic distortion of 0.005%, and a signal-to-noise ratio of 110 dB. The 9B-SST is known for its powerful, clean sound and reliability, with each channel having its own toroidal transformer and power supply, effectively making it a 5-channel monoblock amplifier. Inputs are available on RCA and XLR connectors. The unit is built like a tank, with dimensions approximately 483 x 133 x 483 mm and weighing around 28 to 34.5 kg depending on the version. It was introduced around 2002 and is no longer in current production but remains highly regarded in the audiophile and professional audio communities.
