Bryston 7B Cubed / 7B3mono amplifiers are truly special. Though they do not look much different, they are a big step up from the venerable 4B Cubed / 4B3.

The power supply for this mono-block amplifier is built around a specially-wound transformer that is substantially more efficient than normal. With twice the power available, they can drive all but the most brutal loads to lifelike levels.

But, even at whisper-quiet levels, the Bryston 7B Cubed reveal detail and nuance in your recordings that you never knew existed – until now.
