A rarified few components in audiophile lore have become so ubiquitous that nearly every music lover once had, lusted after, or if they're really lucky, currently owns one. One such legend is the Bryston 4B. This product has been manufactured continuously (though often refined) since 1978. Currently this venerated amplifier is on its 6th generation, and it's never been better. Now rated at 300 watts per channel into 8 ohms, (and upwards of 500 into 4 ohms), this true dual-mono amplifier is powerful enough for practically any speaker, yet it's priced to remain within reach. The degree of clarity, power, nuance, and outright truthfulness of this amp is stunning. If you've always wanted one, maybe now is just the right time.

  • Awarded for Exceptional Value (Doug Schneider, SoundStage!HiFi) Read Review...
  • A well-designed solid-state amplifier should fulfil the purest principles of music reproduction, accepting the input signal, then transparently and harmlessly delivering it to the transducers regardless of their inherent electrical demands, providing effortless and tight control of the drivers while manifesting boundless dynamic expression, detailed resolution and accurate tonality. In the 4B³, Bryston has covered all these bases covered... for at least 20 years. (Edgar Kramer, Audio Esoterica) Read Review...
  • I heard sound that was at once brawny and precise, yet very subtle and refined when the music required it. I’ve said similar things about various amplifiers in the past, but the Bryston was truly remarkable in how it sacrificed little, if any, power output while retaining an extremely sophisticated and nuanced sound that I hadn’t thought possible...  (Roger Kanno, Soundstage!)  Read Review...
  • The latest 4B3 is a masterful and superbly executed amplifier, if you are looking for control, extension, evenness and a whole lot of listening fun it should be very high on your must hear bucket list. I will be very sorry to see it go.  (Jason Kennedy, The Ear)  Read Review... 
  • Bryston's design team appears to have met its stated goal of delivering an overall neutral and natural presentation by ensuring an essentially neutral power response. I liked the sound of the amps so much I requested a review sample of the new 4B Cubed stereo model.  (Maurice Jeffries, Postive Feedback) Read Review...  
  • I actually think that the Bryston 4B³ overall is one of the best amplifiers currently on the market.  (Martin Mertens, Fair Audio)  Read Review...  
  • If you ask about my individual and very subjective opinion, then the Bryston 4B3 seems to be the summit not only of my audiophile, but also my reviewers dreams.  (Jacek Pazio, Sound Rebels) Read Review...  
  • In the STEREO listening room, the Brystons unleashed a kind of unbelievable elemental force, whose pronounced rhythm, texture, and subtlety amaze on closer inspection.  (Tom Frantzen, Stereo Magazine)  Read Review...  
  • So nicely powerful, and its timbre so rich and sonorous that it can be difficult to switch to another amp after listening to a few tracks... Bryston’s latest Cubed series really has taken the sound to a whole new level.  (Christiaan Punter, HFA)  Read Review...

  • The Bryston 4B3 is a top-shelf amplifier that can be considered a benchmark for performance and value -- and a natural addition to our list of Recommended Reference Components.  (SoundStage! Hi-Fi)  Read Review...  
  • Yes, it’s endowed with muscle; it is quick, dynamic, transparent, and has an iron grip of the frequency extremes but what makes the 4B³ most special is its finesse – able to conjure subtleties that engender realism.  (George de Sa, NOVO)  Read Review...  
  • All that said, is the Bryston 4B3 amplifier the best 4B amplifier of all times? Yes, it is that without a doubt according to my opinion! Above and beyond that it is one of the best power amplifiers that one can purchase for love or money.  (Staff Writter, Fidelity Online)  Read Review...  
  • The sonic advances achieved with the new input stage have resulted in a singularity of sorts. This damn thing has perhaps the sweetest, purest top end I have ever encountered in a solid state amp at anywhere near the price (and way beyond), and a tonal finesse that rivals a fine modern tube amp, especially from the mid-bass and into the lower treble. Coupled with the amp's iron-fisted bass range and superbly low noise floor — a combination which allows micro and macro dynamic nuances to shine unimpeded — and you have one helluva performer.  (Maurice Jeffries, Positive Feedback)  Read Review...

  • The 4B Cubed is one of the few amplifiers of which I know where careful listening and a good system set-up can transport one from the doldrums of merely good to the rank of excellence.  (Ernie Fisher, The Inner Ear Magazine)  Read Review...  
  • These dig right to the heart of the music and result in one of the best all-round power amplifiers I have encountered at the price.  (Adam Smith, Hi-Fi News & Record Review)  Read Review...
