- 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. (Philip Beaudette - Soundstage!) Read Review...
- Part Time Audiophile 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? (Marc Phillips - Part Time Audiophile) Read Review...
- High build-quality, versatility, and overall sonic immediacy and clarity are it’s strong points. (Absolute Sound - Best Audio Gear 2022) Read Review...

The Bryston B135 Cubed did better than impress, it let music leave the lasting impression. If we add in the rest of the Bryston package, the company’s 35+ history and 20 Year Warranty, I’d say you’d be hard-pressed to find a more compelling case for a purchase.
High build-quality, versatility, and overall sonic immediacy and clarity are it’s strong points.
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.
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.
