For some, The Bryston 2.5B³ (Cubed) Stereo Amplifier is a gateway drug.

The Bryston 2.5B³ (Cubed) Stereo Amplifier is the least expensive way to get a Cubed Series amplifier, but it's far from "cheap". Made with the same materials and loving care in the Peterborough, Ontario factory as every other Bryston product made, the 2.5B³ will still surprise you with its startling dynamics, crystal clarity and 3D enveloping spaciousness. You've really got to hear one to appreciate what an incredible deal this model is.
