Bryston 4B³ Dual-Mono Amplifier
The Bryston 4B³ Dual-Mono Amplifier reproduces exactly what is captured in a recording without exception and without added distortion is our benchmark.
A rarified few components in audiophile lore have become so ubiquitous that nearly every music lover once had, lusted after, or if they’re really lucky, currently owns one.
One such legend is the Bryston 4B. This product has been manufactured continuously (though often refined) since 1978. Currently this venerated amplifier is on its 6th generation, and it’s never been better.
Now rated at 300 watts per channel into 8 ohms, (and upwards of 500 into 4 ohms), this true dual-mono amplifier is powerful enough for practically any speaker, yet it’s priced to remain within reach. The degree of clarity, power, nuance, and outright truthfulness of this amp is stunning. If you’ve always wanted one, maybe now is just the right time.

Reviews
- All that said, is the Bryston 4B3 amplifier the best 4B amplifier of all times? Yes, it is that without a doubt according to my opinion! Above and beyond that it is one of the best power amplifiers that one can purchase for love or money. Staff Writer | Fidelity Online
- The sonic advances achieved with the new input stage have resulted in a singularity of sorts. This damn thing has perhaps the sweetest, purest top end I have ever encountered in a solid state amp at anywhere near the price (and way beyond), and a tonal finesse that rivals a fine modern tube amp, especially from the mid-bass and into the lower treble. Coupled with the amp’s iron-fisted bass range and superbly low noise floor — a combination which allows micro and macro dynamic nuances to shine unimpeded — and you have one helluva performer. Maurice Jeffries | Positive Feedback
- The latest 4B³ is a masterful and superbly executed amplifier, if you are looking for control, extension, evenness and a whole lot of listening fun it should be very high on your must hear bucket list. I will be very sorry to see it go. Jason Kennedy | The EAR

World Class Engineering
Bryston amplifiers are world famous for all the right reasons. Some of the most well known movies and music were recorded in studios using Bryston amplifiers. You can get the studio sound at home.
All Bryston amplifiers are engineered and manufactured in their state-of-the-art facility in Ontario, Canada to precise tolerances using top quality materials. Each product is then tested for 100 hours before it leaves the building and includes a thorough inspection report so you can see just how well your unit performs.
Then, they guarantee its excellent performance and trouble free operation for 20 years – an industry first! Whether your goal is lifelike stereo sound, Hollywood cinema experience at home, or music throughout your home, Bryston amplifiers will satisfy your craving for the best sound reproduction available.
Zero Compromise
Every amplifier is built to be a crystal clear window into the music. Each channel is fully independent including its own power supply and transformer regardless of how many channels are in a package. Even the integrated amplifiers use identical amplifier channels to their equally rated separate equivalents.
Convection Cooled
Bryston amplifiers are entirely convection cooled. That means even at full power, they can dissipate heat passively with our computer optimized heat sinks. Fans get noisy, collect dust, and can eventually fail. Bryston wants you listening for a lifetime.
Make it Yours
Your system should look as great as it sounds. Make Bryston amps your own by choosing from different dress panel options.
Nearly all models are available with black or silver anodized aluminum dress panels. You might prefer the clean lines of our 17 inch wide panels, or the athletic stance of our 19 inch panels which include front mounted handles. Choose classic green indicator LEDs or the bold look of modern blue.
