In 1973, engineer Chris Russell took his PRO 3 prototype amplifier to a studio in Toronto for an audition and received an order for 2 units. Nearly 5 decades later, that design has evolved into the Bryston 3B Cubed. It delivers twice the power of the original and uses the same technology as the 4B. Its shallow depth is suited to installations where cabinet space is limited.
