Bryston 9B³ Cubed Multichannel Power Amplifier

Reference-Grade Performance. Modular Flexibility. Legendary Bryston Engineering.

The Bryston 9B³ Cubed Multichannel Power Amplifier brings the exceptional clarity, dynamic authority, and musical refinement of Bryston's acclaimed Cubed Series to high-performance home theater and multichannel audio systems.

Available in 3-, 4-, or 5-channel configurations, the 9B³ delivers 200 watts per channel into 8 ohms and 300 watts per channel into 4 ohms, providing the power and control necessary to drive demanding loudspeakers with remarkable precision.

Whether you're building a dedicated home theater or upgrading an existing surround sound system, the 9B³ offers extraordinary performance and long-term flexibility.

Independent Power for Every Channel

Unlike conventional multichannel amplifiers that share a single power supply, the Bryston 9B³ features independent amplifier modules, each with its own dedicated toroidal transformer and power supply.

This sophisticated architecture minimizes interaction between channels and preserves exceptional dynamic performance, even during demanding movie soundtracks.

The result is outstanding channel separation, precise imaging, and effortless reproduction of both music and cinematic effects.

Bryston Cubed Series Technology

The 9B³ incorporates Bryston's patented Salomie input circuitry, engineered to minimize distortion and noise while preserving the natural character of the original recording.

From the quietest musical details to the most powerful cinematic passages, the amplifier maintains exceptional transparency, tonal accuracy, and control.

Modular Design That Grows With Your System

One of the 9B³'s greatest advantages is its modular construction.

Choose the configuration that best matches your system:

• 3 Channels: Ideal for powering front left, center, and right loudspeakers.

• 4 Channels: Excellent for specialized surround or multichannel applications.

• 5 Channels: A complete amplification solution for traditional five-channel home theater systems.

Additional amplifier modules can be installed as your system requirements evolve.
