The Canadian-made Bryston, 4B ST Power Amplifier is a 250 watt per/channel @ 8ohm powerhouse. The basic design was initially introduced in 1972 and has been a staple for the company since its founding 50+ years ago, with some tweaks along the way. The 4B ST is a modified Class A/AB amplifier which launched in the late 1980s. It features a very stable output stage, one dedicated for each channel, and a signal-to-noise ratio of 108 dB. This “dual-mono” layout allows for exceptional stereo separation. The amplifier can also be run bridged for 600 watts of total output power into one speaker. It has a solid-state design with a wide bandwidth and low output impedance. The 4B ST is known for its high-end sound quality.

One highly relevant reviewer said the "4B ST totally eliminated mechanical sounds that might have overlaid the music in any way"... another states emphatically, "the 4B ST provides high-end sound that can compete with components costing twice as much". There's a reason many of the top loudspeaker brands brought Bryston amps with them to shows as they best drive there speakers to their absolute sonic limits.

This is a perfect example of the type of workhorse the 4B ST was, and still is today. Dynamics on this amp are incredible, with detail, and power to spare for those BIG moments in both music and movie passages. This unit has been reviewed by our tech with a clean bill of health.
