The 3B³ is Bryston’s versatile high-performance stereo amplifier, delivering the speed, control, and transparency of the Cubed Series platform in a more compact and system-friendly form factor. Built around Bryston’s patented Salomie input stage circuitry, the 3B³ combines excellent detail retrieval with the effortless musicality and reliability the brand is known for.
What makes the 3B³ especially appealing is its balance of refinement and drive. It delivers tight, controlled bass, open midrange clarity, and stable imaging while maintaining a relaxed and natural tonal character that works beautifully across a wide range of loudspeakers. The fully balanced architecture and convection-cooled chassis also contribute to exceptionally low noise and long-term dependability.
With 200 watts per channel into 8 ohms and up to 300 watts per channel into 4 ohms, the 3B³ offers more than enough authority for serious two-channel systems while preserving the smooth, unforced presentation that makes long listening sessions enjoyable.
Available in Silver or Black finishes.
