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.

At Last! A Grinder That Can Grind Flaxseed!!!
Color: Silver single
I'm so excited -- my search for a manual flaxseed grinder is over! After spending countless hours -- nay, days & weeks! -- searching for a simple, manual spice grinder that worked well for flaxseeds, I found this little $7 gem! Just got it today & immediately tested it out... with GREAT results! At first I was disappointed to see that the grinding mechanism is plastic, but it sure did the job! It has a little dial to adjust the coarseness, which is nice. Also love that the container is glass; and larger than I thought. Easy to refill & I expect it'll be easy to clean. I think the ease of grinding will depend on how tightly or loosely you adjust the dial; at its tightest, I couldn't twist it at all, but loosening it allowed me to use it easily and it still gave me a fine grind. Highly recommend it... can't beat the value!

Pepper grinder works as expected, I'm concerned about its long-term durability.
Color: Silver single
Good product, grounds pepper as expected. I was almost surprised that the grinder is plastic rather than metal. I'm not sure of its long-term durability

Perfect
Color: Silver single, Color: Silver single
Excellent salt grinder This ceramic grinder surprised me for its good quality. The design is very elegant, with the stainless steel part and the glass jar that allows you to easily see how much product is left inside. It feels solid and well built. The ceramic grinding mechanism works very smoothly and crushes the salt evenly. In addition, it is easy to refill and clean, which is very practical to use in the kitchen every day. It has a perfect size: it does not take up much space but has good capacity. Without a doubt it is a very useful and beautiful product for the table or the kitchen. I totally recommend it!
