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.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.

Believe the Reviews
Color: Cooling Blue Cover, Size: King (Pack of 2)
I purchased these pillows because we were in need of new pillows, I previously had allswell pillows which were from walmart and they were good to start but now they tragically became very sparse and it started to effect my sleep so I saw these after careful review on other pillows and reviews I came across these and I saw some reviews and videos and I ordered them.. first they are king size we ordered they are perfect for the bed, they are plump and soft, they are memory foam which has always worked out for me for support and kept it’s shape these are great it did have a little smell I guess from packaging but other than that they are a huge upgrade from what we had before! I’m excited because they are cooling too! for the price point can’t beat it and this is coming from someone who was about to spend money on a purple pillow this will be good for now definitely buy it.
