Bryston - 9B³ - Modular Multi-Channel Power Amplifier

The 9B³ is Bryston’s flexible high-performance multi-channel amplifier platform, designed for serious home theater and immersive audio systems that demand the same refinement, control, and reliability as the company’s legendary two-channel amplifiers. Built around Bryston’s Cubed Series technology and patented Salomie input stage circuitry, the 9B³ delivers exceptional clarity, dynamic authority, and low-noise performance across every channel configuration.

What makes the 9B³ especially unique is its modular architecture. Available in configurable 3, 4, or 5 channel layouts, the amplifier can be expanded later as your system evolves, making it an ideal long-term centerpiece for high-end surround systems. Dialogue remains focused and natural, effects are rendered with precision and scale, and bass stays tight and controlled even during demanding cinematic passages.

Its fully balanced architecture, convection-cooled chassis, and independent channel regulation all contribute to remarkable stability and long-term reliability. Whether used in dedicated theaters or premium multi-channel music systems, the 9B³ delivers the effortless, transparent presentation Bryston is known for.

Available in Silver or Black finishes.
Configurable 3, 4, or 5 channel architecture with field-upgradeable modular channel expansion.
Additional faceplate and rack mount configuration options available.
