About the 3B-ST
The Bryston 3B-ST is a solid-state stereo power amplifier with a class-AB2 output stage, delivering 120 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, with 400 watts available in bridged mono mode. It features a dual-mono design with separate power supplies for each channel, including two 225 VA toroidal transformers and large smoothing capacitors for stable power delivery. The amplifier has balanced XLR and unbalanced RCA inputs, selectable gain settings, and a soft-start power control to prevent line surges. It is built with a rugged, compact chassis that acts as a heatsink and includes clip-sensing LEDs for protection and monitoring. The 3B-ST is known for its very low distortion (0.007% THD+N), high damping factor (>500), wide frequency response (1 Hz to 100 kHz), and excellent signal-to-noise ratio (106 dB). It weighs 22 lbs and measures 19" W x 5.25" H x 9" D. Manufactured in Canada, it is praised for its neutral sound and reliability, making it a popular choice for audiophiles seeking transparent amplification.
