B135 Cubed Integrated Amplifier

B135 Oblique silver 17-web

 If I needed a compact music-making machine that didn’t take over my living space, the B135³ would be among my first choices. It thrived in a number of configurations, always doing what it was meant to do. What more do you need? Full Review

Steve Holding


"In short, it didn’t matter what genre of music I played, what loudspeakers I used with it, or what playback levels I used, from
whisper-quiet levels to ear-shattering, the Bryston B135-SST² performed impeccably through-out, delivering the music exactly
as the performers and engineers intended, without added noise or distortions and without any frequency aberrations at all. Incredibly good performance that’s a gilt edged investment in good sound."

Philip Beaudette


"You’ll have to spend significantly more to improve on the B135’s sound, and even so, those improvements are likely to be small. On these grounds -- and because it sounds so darn good -- Bryston’s B135 SST2 gets my highest recommendation."
