The Bryston 7B³ is a premium monoblock power amplifier that represents the second-largest in Bryston's mono amplifier hierarchy. It features a fully balanced, Class AB design housed in a machined aluminum chassis with convection cooling and no moving parts. The amplifier is renowned for its extreme clarity, detail resolution, and ability to drive a wide range of speaker loads with virtually perfect freedom from overload. The Cubed Series represents an evolution from the previous generation, with improvements focused on the input stage featuring a new patented circuit by Dr. Alexandru Salomie that delivers measurable distortion less than 1/1000th of 1 percent. Each amplifier undergoes 100 hours of factory testing before shipment and comes with an individual specification sheet documenting its exact performance. The 7B³ won an Editors' Choice Award from The Absolute Sound magazine and is backed by Bryston's legendary 20-year warranty.
