The Bryston 3B Cubed: A Modern Legend with Studio Soul

In 1973, a prototype amplifier, the PRO 3, earned its place in a top recording studio on its very first audition. That legendary DNA, refined over nearly five decades of relentless engineering, lives on in the Bryston 3B Cubed. It’s an amplifier with a direct lineage to the professional world, built to deliver breathtaking realism and unflinching reliability in your home.

The Power of Purity, Distilled While it traces its heritage back to the studio, the 3B Cubed is a thoroughly modern powerhouse. It incorporates the same exclusive, patented technologies—like the remarkable Salomie circuit—found in Bryston's most venerated Cubed Series amplifiers. It shares the same sonic heart as its famous bigger brother, the 4B, offering that same level of transparency, detail, and control in a more compact and versatile form factor.

At its core is a true dual-mono design, with fully independent power supplies and transformers for each channel. This uncompromising architecture delivers a vast, stable, three-dimensional soundstage and unlocks a powerful 200 watts per channel (up to 300 into 4 ohms). This is power with purpose: an iron-fisted grip that commands your speakers, revealing effortless dynamics and subtle nuances in every recording.

 

Intelligently Designed for the Real World Beyond its sonic prowess, the 3B Cubed is an intelligent choice for any high-performance system. Its refreshingly shallow chassis depth makes it ideal for installations in custom cabinetry or racks where space is at a premium. Switchable gain settings ensure perfect synergy with any preamplifier, while its fanless, convection-cooled design guarantees completely silent operation. For the professional or custom installer, the PRO version adds rack mounting and rear-panel trim controls for precision calibration.

As with all Bryston components, the 3B Cubed is built to a standard, not a price. This commitment to excellence is backed by the legendary Bryston 20-year warranty, ensuring an investment that will deliver breathtaking musical realism for decades to come.

  • True Dual-Mono Design: Two channels, each with a fully independent power supply and transformer for ultimate channel separation.

Fantastic foam!
Color: Black, Color: Black
Bought this so I can cut down on my trips to Starbucks and recreate those drinks "to go" at home. It works for making any kind of foam...most recently been whipping up 1/8c half n half with it and added syrups for my iced coffees I take to work. Soooooo worth the money. Starbucks quality foam (if you're not a coffee snob) at home. I now enjoy having iced coffees with salted caramel or chocolate creme cold foam that costs less than $2 to make at home versus $15 at the drive-thru. Time & money saved!

Favorite kitchen gadget!
Color: Black
I bought this for mixing powdered mixes into water, and boy do I love it. I honestly use it way more than anticipated and it works so well. I use it for everything from whisking formula to the intended purpose of frothing milk. Blends quickly and clean is easy, just put a couple of drops soap into water and turn on them rinse! Best money I've spent recently on something for the kitchen, don't even hesitate, just buy it!

Spiral portion of blender did not hold up
Color: Black
It was wonderful for 10 weeks. We used it almost daily and sometimes twice a day. It frothed quickly. It proved a satisfying blender until approx 10 weeks of use. The wire spiral on the end started to slowly wind off. It worked OK but wobbled and frothed weakly at that point. For short term use, for very infrequent use, it will be fine. Looks acceptable, easy to use. Changed the batteries one time. For the price, I am not unhappy. Have now replaced it with a more expensive one on Amazon. Thank you Amazon for giving your shoppers the opportunity to leave our feedback. It is one of your most appreciated features.
