About the 2B-SST2
The Bryston 2B SST2 is a refined version of the classic 2B amplifier, originally introduced in 1979. It provides 100 watts per channel into 8 ohms with very low distortion and noise, featuring selectable balanced (XLR) or single-ended (RCA) inputs and adjustable input sensitivity (1V or 2V). The amplifier uses SST2 technology for improved sonic performance, including a new soft-start power switch, RF input filter, and upgraded capacitors. It is built with fully discrete analog components, gold-plated connectors, and a robust extruded aluminum and steel chassis for durability. The 2B SST2 supports bridging for higher power output (up to 350 watts into 4 ohms bridged), has a damping factor over 500, and a frequency response from below 1 Hz to over 100 kHz. It includes a 12V trigger for remote power control and features tri-color LEDs indicating operational status. Known for its exceptional build quality and sonic clarity, the 2B SST2 is suitable for demanding audiophile stereo setups and multi-amplified speaker systems.
