Description

3B Cubed Dual-Mono Amplifier

Way back in 1973, a young engineer named Chris Russell took his new prototype amplifier, the PRO 3, to an A list studio in Toronto for an audition. He left with an order for two. Nearly five decades later, that amp has evolved into the Bryston 3B Cubed. It's twice as powerful as the original and ten times as impressive. Though it's one of our smaller amplifiers, it features all the same technology found in our venerable 4B. One big advantage, however, is the shallow depth. The 3B Cubed is a great all around amp, but is especially useful for shallow mounting depth applications.

Features

  • Balanced XLR and Single ended RCA input
  • 2 Channels each with fully independent power supplies including transformers
  • 200W into 8 ohms (and up to 300 into 4 ohms) per channel
  • The patented Salomie circuit found in all Cubed Series amplifiers
  • Switchable gain (23dB or 29dB)
  • Fully convection cooled means no noisy fans
  • Machined and anodized aluminum enclosure and dress panel
  • Less than 500mW standby power consumption
  • SoftStart microprocessor controlled startup sequence won't trip circuit breakers
  • DC trigger for automated turn on and turn off
  • Legendary Bryston 20 Year Warranty

Options

  • Silver or black faceplate
  • 17” or 19” faceplate (non-rack mountable) 19" comes with front mounted handles
  • PRO version includes 19" rack mount dress panel in black plus rear panel channel trim pots (-14 to 0dB)

Reviews

After our extensive tests, we can conclude that with the 3B³ you really get a heck of an amplifier. A powerhouse that is not only enormously robust, but also plays with delicate, almost surgical precision. We can only say that the 3B³ belongs in the absolute reference class.

The interesting thing about the new sound is that it is smoother and warmer, yet still comes across as completely neutral, and with a refinement and low-level resolution that leaves nothing to be desired. The most amazing quality perhaps is in the treble, which is supremely subtle and decidedly non-edgy, even with the most critical speakers.

Last but not least, a very exciting insight: Whether it's the high damping factor or the broadband - the Bryston power amp has perfectly harmonized with all my speakers and literally made the most of them.

Why Choose Bryston

Bryston has built its reputation on a clear, unwavering philosophy—accuracy, control, and long-term reliability. Every unit is made in Canada, typically to order, ensuring current production standards, and backed by an industry-leading 20-year warranty on amplifiers.

Signature Design and Sound

Manufactured in Canada, Bryston products are engineered around fully discrete analogue circuitry, substantial linear power supplies, high-current output stages, and extremely conservative thermal and electrical operating margins designed for long-term reliability and consistent performance.

One of the defining characteristics of Bryston amplification is its remarkable sense of control and dynamic stability. Rather than sounding overtly warm or artificially romanticised, Bryston amplifiers deliver music with excellent neutrality, bass authority, transient speed, and low-noise transparency. The presentation feels highly composed and revealing while still maintaining strong musical engagement and long-term listenability.

The legendary 4B amplifier series helped establish Bryston’s worldwide reputation through its ability to drive difficult loudspeaker loads with ease while maintaining composure and clarity under demanding listening conditions. That same philosophy continues throughout the current range, including products such as the Bi-200 integrated amplifier, which combines impressive current delivery, analogue refinement, and modern connectivity within a highly versatile platform.

Bryston’s digital ecosystem also extends into streamers, DACs, CD playback, and network audio platforms with strong integration support for both Roon and Audirvana systems, allowing customers to build highly cohesive modern Hi-Fi systems around the Bryston platform itself.

Bryston Product Range

The Bryston range available through HeyNow Hi-Fi includes integrated amplifiers, stereo and mono power amplifiers, preamplifiers, DACs, music streamers, CD players, and network audio products designed for serious long-term ownership and reference-level system performance.

Products are manufactured in Canada in relatively limited production volumes, ensuring careful quality control and ongoing refinement throughout the range. Because of this, Australian availability can sometimes become limited between manufacturing runs. When local stock is available, it often presents an excellent opportunity for customers to secure current-production Bryston products without extended international lead times.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with amplifier matching, streamer integration, digital system configuration, and complete system optimisation to ensure Bryston products perform at their full capability within each customer’s listening environment.
