9B³ Modular Multi-Channel Power Amplifier

Special Order

Bryston's 9B is a legendary line of multi-channel amplifiers. This new Cubed iteration lifts the performance of theaters and other multi-channel applications to new heights far beyond expectations set by inferior options. Now with each channel capable of 200 watts, more speakers than ever before can be driven with ease. Unlike most multi-channel amplifiers and receivers, the all new 9B Cubed features up to 5 self contained channels. Since each has a fully independent power supply, high output on one channel won't be a drag on the others, so every note will be dynamic and clear.

Network monitoring and control is built into every unit to make integration with home automation systems easy. Keep tabs on the temperature, see overdriving warnings, and even mute individual channels all from the amp's own webpage.

Best of all, the new 9B Cubed brings Bryston's patented Salomie circuit to a 5 channel form factor for the first time. Finally, you can have a multi-channel amplifier that sounds as great as our others.
