3B Cubed Dual-Mono Amplifier

Way back in 1973, a young engineer named Chris Russell took his new prototype amplifier, the PRO 3, to an A list studio in Toronto for an audition. He left with an order for two. Nearly five decades later, that amp has evolved into the Bryston 3B Cubed. It's twice as powerful as the original and ten times as impressive. Though it's one of our smaller amplifiers, it features all the same technology found in our venerable 4B. One big advantage, however, is the shallow depth. The 3B Cubed is a great all around amp, but is especially useful for shallow mounting depth applications.

  • Switchable gain (23dB or 29dB)

  • DC trigger for automated turn on and turn off
  • Legendary Bryston 20 Year Warranty

  • 17” or 19” faceplate (non-rack mountable) 19" comes with front mounted handles
  • PRO version includes 19" rack mount dress panel in black plus rear panel channel trim pots (-14 to 0dB)

Reviews

After our extensive tests, we can conclude that with the 3B³ you really get a heck of an amplifier. A powerhouse that is not only enormously robust, but also plays with delicate, almost surgical precision. We can only say that the 3B³ belongs in the absolute reference class.

Alpha Audio

The interesting thing about the new sound is that it is smoother and warmer, yet still comes across as completely neutral, and with a refinement and low-level resolution that leaves nothing to be desired. The most amazing quality perhaps is in the treble, which is supremely subtle and decidedly non-edgy, even with the most critical speakers.

Last but not least, a very exciting insight: Whether it's the high damping factor or the broadband - the Bryston power amp has perfectly harmonized with all my speakers and literally made the most of them.

Perfect size and amount for family travel
Size: 3 Fl Oz (Pack of 6), Style: SPF 50
My usual brand raised its prices, leaving me in a bind to find a cheaper alternative that works well and is suitable for our family trips. I stumbled upon this brand and decided to give it a try. The travel-sized multi-pack is priced reasonably, and I received it promptly. I’ve decided to make this brand my go-to for travel products.

My favorite sunscreen
Size: 5 Fl Oz (Pack of 1)
The BEST sunscreen I have tried. I LOVE this unscented Coola. It goes on smooth and doesn’t feel sticky at all, you will forget you have it on. It truly is unscented and so light. It’s also effective protection from the sun.

One of the few body sunscreens that doesn't trigger my sensory issues
Size: 5 Fl Oz (Pack of 1)
I have sensory sensitivities, so wearing sunscreen is usually a pretty unpleasant experience for me. I can't stand heavy textures, greasy finishes, or that sticky sunscreen feeling that seems to sit on top of the skin all day. I'm also bothered by mineral and matte sunscreens that dry my skin out. It's very hard to find a sunscreen as genuinely comfortable as this one is. I bought the Coola Sunblock Body Lotion because several reviews mentioned that it actually feels like a regular lotion once applied, but I honestly assumed it still wouldn't work for me. I was genuinely shocked the first time I used this. The texture feels silky and lightweight, absorbs quickly, and leaves my skin feeling soft rather than coated or oily. It really does wear more like a comfortable body lotion than a traditional sunscreen, and I don't notice any residue or oily feel at all, which is amazing. I also love that it's fragrance-free, which makes it even easier for me to tolerate, especially with sensitive skin and sensory issues. Coola Sunblock Body Lotion is one of the very few body sunscreens I've tried that I actually enjoy wearing, and it works perfectly. I am very fair and burn easily, but I had no burning or redness on my first outside day of the summer while wearing this. It's sunscreen that works and that I can actually wear with zero discomfort. Amazing.

Love the quality!
Size: 5 Fl Oz (Pack of 1)
Im 63, with fair and sensitive skin. I love this high strength sunscreen that isn't greasy and doesn't have added ingredients and perfumes that bother me and make me break out.
