Bryston Ltd. is a well-known and very well-respected Canadian audiophile electronics company based in Dwight, Ontario, a region of Canada far more famous for a relaxing summer life and great ice cream than a place that you might expect to find world-class electronics. Bryston has been designing and manufacturing consumer and professional audio equipment for 50 years. Renowned for its reliability, Bryston has built a strong reputation in the audiophile community for offering an exceptional 20-year warranty on its analog products. Dwight is also known as a summer retreat for many wealthy and famous individuals. The Bryston 4B Cubed amplifier is a classic Class A/B amplifier. This amp, in some version or another, has been in production continuously since 1978. The version I reviewed is the sixth generation. It’s pretty incredible that this amplifier has only needed to be updated six times in 46 years. The Bryston 4B3 amplifier produces a reported 300 watts at eight ohms and 500 watts into four ohms, and features both balanced and unbalanced inputs. It weighs 42 pounds, and it comes in either 17 or 19 inches wide (depending on the front plate you choose), is 6.3 inches high and 15.5 or 17.75 inches deep, depending on whether you get it with the front handles or not.
