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.

Features

  • Balanced XLR and Single ended RCA input
  • 2 Channels each with fully independent power supplies including transformers
  • 200W into 8 ohms (and up to 300 into 4 ohms) per channel
  • The patented Salomie circuit found in all Cubed Series amplifiers
  • Switchable gain (23dB or 29dB)
  • Fully convection cooled means no noisy fans
  • Machined and anodized aluminum enclosure and dress panel
  • Less than 500mW standby power consumption
  • SoftStart microprocessor controlled startup sequence won't trip circuit breakers
  • DC trigger for automated turn on and turn off
  • Legendary Bryston 20 Year Warranty

Options

  • Silver or black faceplate
  • 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.

This is an inexpensive quality knife set!
Size: 18-Piece, Style: Traditional Handle Design, Size: 18-Piece, Style: Traditional Handle Design
I have been a Chef for 17 yrs. and from experience know you don't get quality in an inexpensive knife set. This AmazonBasics Premium set really impressed me. The knives I use and have at home are mixed matched because I like good hefty knives. My wife always rags on me that the knives look crappy, so I got on here and started reading reviews. I was not gonna spend alot of money on a set knowing that I have good knives already. Then I saw this set, and looked at the video. I got them in TWO days, and when I opened the package I was expecting the block to be split, chipped, or have saw marks. As you can see the one I got was flawless. I then took out the chefs knife and smiled. Easily comparable to a 8" Zwilling JA Henckels Pro Traditional Chefs Knife. It has the same quality, heft, and balance. TRUST ME I KNOW!!!! Beautiful knife. The thickness of the blade is equal to my Victorinox Fibrox Chefs Knife and I paid $45. for that knife alone!!! This here is a quality product at a good price. Treat them with respect and they will last for YEARS. If your looking for a good complete set, a nice wedding gift, of just looking to replace the "crappy" set you have look no further.

Amazing for the price
Size: 9-Piece, Style: Traditional Handle Design
At a higher price they would have been 4 or 3 stars, but for $50 this is an insane deal. The steel is pretty good quality. It almost seems like it's hardened VG-10 but I think they would advertise that if it were so I'm guessing it's a cheaper stainless steel that just comes harder without being treated though I'm just speculating based on price. Anyways they're flat ground, take an edge easily, and hold it reasonably well. Nicer knives would certainly hold an edge longer but I'm pretty happy with them. The flat ground shape of the blade is actually ever so slightly convex as well, it's not too apparent in use but you can certainly see it in the reflection. The serration on the bread knife is the inverse of what I would prefer, rounded metal with points cut into it vs points extending from the blade with the rounded parts cut out. When the rounded parts are cut out it's easy to sharpen. When the points are cut out it's almost impossible to sharpen. The handles are the downfall of the knives. They're not smoothly finished and while they look alright they feel like a cheaply cut (although very solid) piece of plastic which is exactly what they are. A little bit better finishing on the handles would really improve the knives. The holding block serves it's purpose well. The sharpener is ok but below average, though the rough steel rod sharpeners just aren't great to begin with. Diamond coated rods are much better, though ceramic rod sharpeners are the best. Overall I love the knives and I'm glad I bought them. For the price they're the best deal I've ever found, no question. I love that there is no logo on them, but I just don't like to see branding in general even if it's a premium brand. If you're buying this for the bread knife or the sharpener, don't, they're not good. If you want the look and feel of a $300+ knife set, don't buy this, you'll be disappointed. If you want a good quality knife set but aren't willing to spend $300+ then absolutely buy these, they're great.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.
