7B³ mono amplifiers are truly special. Though they don't look much different, they're a big step up from the venerable 4B³. The power supply for this amplifier is built around a specially wound transformer that is substantially more efficient than normal. With twice the power available, they can drive all but the most brutal loads to lifelike levels. But even at whisper quiet levels, they reveal detail and nuance in your recordings that you never knew existed until now.

  • Up to now I have never heard this kind of quality from any other amplifier. (Jörg Dames - Fair AudioRead Review...
  • Up to now I have never heard this kind of quality from any other amplifier. Jörg Dames Fair Audio The sort of musicality I hear in the Brystons is more along the lines of a winning, agile tunefulness than a beguiling, silky lusciousness. I kept listening to cut after cut not necessarily because every nuance was brought forth, but because the Brystons seemed to convey a feeling of unfettered directness and immediacy. I remained engaged with the music during long listening sessions, my feet tapping to the beat and my head leaning with the phrases, because the Brystons’ readily transmitted the central “musical core”—if you will. Kirk Midtskog The Absolute Sound Overall, the 7B-3s are probably as delightful-sounding as any amps I've auditioned. They are completely without a familiar sonic signature, yet immensely melodious and transparent, and absolutely effortless in reproducing the kind of dynamic range one may get at live performances of large orchestral music. Ernie Fisher The Inner Ear If you're looking for fairly universal amplifiers that can drive even the most difficult speakers strongly but also with extreme sensitivity when prompted by the music, do not miss the opportunity of listening to these machines; do not be deceived by the relatively affordable cost. They are worth much more than required, when compared to the competition. (Angelo Jasparro - Audio Activity) Read Review...
  • The Bryston BP-173 Preamplifier and the Bryston 7B3 Mono Amplifiers is an amazing setup, and should be on any serious short list. The entire Bryston Cubed Series component line should be evaluated, as well. Excellent products with outstanding support. Highly, highly recommended. (Dwayne Carter - Enjoy The Music) Read Review...
