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.

Core Features:

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

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
