Bryston 14B³ Cubed 2.0 Stereo Power Amplifier

The Bryston 14B³ Cubed 2.0 delivers the kind of power normally associated with a pair of monoblock amplifiers from a single stereo chassis.

With 600 watts per channel into 8 ohms and 900 watts per channel into 4 ohms, the 14B³ is built for serious loudspeakers and systems where effortless power, control and dynamic headroom are essential.

But the 14B³ isn't simply about brute force. Each channel has its own fully independent power supply and transformer, creating a true dual-mono architecture designed to combine massive output capability with the low noise, resolution and neutrality Bryston's Cubed Series is known for.

600 Watts Per Channel

The numbers are substantial:

• 600 watts per channel into 8Ω
• 900 watts per channel into 4Ω

That gives the 14B³ the ability to drive large, demanding loudspeakers with tremendous authority.

More importantly, that kind of reserve means the amplifier doesn't have to work near its limits during demanding musical passages. It has the headroom to handle large dynamic swings while maintaining control of the loudspeaker.

Dual-Mono Architecture

Inside the 14B³ are effectively two independent amplifier channels.

Each channel receives its own dedicated power supply and transformer, minimizing interaction between the left and right channels and providing each loudspeaker with its own substantial reserve of power.

It's one of the defining differences between the 14B³ and a conventional high-powered stereo amplifier.

You get much of the electrical independence associated with monoblocks while keeping the entire amplifier in a single chassis.

Bryston Cubed Series Technology

The 14B³ incorporates Bryston's patented Salomie circuit, found throughout the Cubed Series amplifier lineup.

The design focuses on reducing noise and distortion while preserving speed, transparency and dynamic capability.

Total harmonic distortion plus noise is rated at less than 0.005% from 20Hz to 20kHz at rated power into 8 ohms.

The 14B³ may have enormous power reserves, but the goal is still accurate reproduction of the signal rather than adding a particular sonic signature.

Balanced XLR & RCA Inputs

The Bryston 14B³ provides both:

• Balanced XLR inputs
• Single-ended RCA inputs

Switchable 23dB or 29dB gain provides additional flexibility when matching the amplifier with different preamplifiers and source systems.

A 12V DC trigger allows automated power control when the amplifier is used with compatible preamplifiers, processors or control systems.

Passive Cooling — No Fans

Despite its enormous output capability, the 14B³ is fully convection cooled.

There are no cooling fans adding mechanical noise to the listening room.

Bryston also incorporates a microprocessor-controlled SoftStart sequence to manage the amplifier's substantial startup current and help prevent nuisance circuit-breaker trips when the amplifier is powered on.

Standby power consumption is less than 500mW.

Built Like a Bryston

The 14B³ is a serious piece of hardware.

Its substantial machined and anodized aluminum chassis weighs approximately 91 pounds, providing the physical structure and heatsinking required for an amplifier of this scale.

It's built in Canada and backed by Bryston's 10-year warranty.

That long warranty has become one of the defining characteristics of Bryston electronics and reflects the company's focus on building amplifiers intended for long-term ownership.

Available Configurations

The Bryston 14B³ Cubed 2.0 is available with several front-panel configurations:

• Consumer faceplate without handles
• Consumer faceplate with handles
• PRO rackmount faceplate
• PRO rackmount faceplate without handles

This allows the 14B³ to work equally well in a dedicated high-end listening room or professionally installed audio system.

14B³ or a Pair of 7B³ Monoblocks?

This is where the 14B³ becomes particularly interesting.

Both the 14B³ and 7B³ deliver 600 watts into 8 ohms and 900 watts into 4 ohms per channel.

The difference is configuration.

A pair of 7B³ amplifiers gives you completely separate monoblock chassis, while the 14B³ places two independently powered amplifier channels into one substantial enclosure.

For listeners who want monoblock-level Bryston power without adding two separate amplifier chassis to the room, the 14B³ is an extremely compelling solution.

Experience Bryston at The Grid HiFi

The Grid HiFi is your Bryston and high-end audio expert in Houston, Texas.

An amplifier with 600 watts per channel opens the door to some of the most demanding loudspeakers in high-end audio, but simply having more power isn't the objective. The amplifier still needs to be properly matched to the speakers, preamplifier and room.

The Grid can help determine whether the 14B³ is the right amplifier for your system and match it with the appropriate preamplifier, DAC, streamer, turntable, phono stage, loudspeakers, subwoofers, cabling and equipment support.

For a system that needs massive power without moving to separate monoblocks, the Bryston 14B³ is one of the most serious stereo amplifiers in the Bryston lineup.
