Bryston proves that integrated amplifiers give no ground to their separate counterparts. The B135 is literally constructed of the BP-17 preamplifier and 2.5B Cubed amplifier into a single chassis offering the best of both products without occupying extra space and costly interconnects. For those who wish to save money and space yet refuse to yield sound quality, the B135 Cubed Integrated Amplifier is a top choice.
