OUR MISSION To design a state of the art 1000 watt power amplifier that does not compromise performance at 1/10th power.A significant part of the design criteria for the 28B SST2 was to develop a very powerful amplifier that would drive any speaker on the planet but maintain an ideal power curve at 1 watt as well as at 1000 watts and every power level in between. Most amplifiers exhibit a power curve whereby the best noise floor, drive capability and distortion is maintained from about 1/3 power and up. The Bryston 28B-SST2 Mono amplifier maintains its power curve right from the first watt. This results in a BIG POWERFUL amplifier that sounds incredibly detailed and musical at very low levels and maintains that same sophistication and drive capability with even the most difficult, inefficient speakers, large or small.The Bryston 28B-SST2 is a fully balanced output amplifier (BRIDGED), which has reduced THD and IMD to unprecedented low values, (typically 0.001% or less), for a new degree of transparency, musicality and ease of listening. Superbly low noise floor, typically below – 115dB, yields an inky black silence between notes for hauntingly realistic reproduction. Tremendous power reserves give the 28B-SST2 virtually perfect freedom from overload on any type of speaker or music, bringing the performance and realism directly into your listening environment. The 28B’s ability to resolve subtle musical details has to be heard to be believed – it truly sets a new standard : Mission accomplished.


OUR GOAL For over 30 years, Bryston has had a continuing commitment to design and manufacture the most accurate and reliable audio electronics. The performance, value, and reliability of our amplifiers, and our unrivaled warranty, have brought us recognition in the world of pro audio, as well as with reviewers and home users. But there is no product that cannot be made better. To this end, we maintain an extensive research and development program, constantly investigating techniques, technologies, and devices that promise improvements to all aspects of our amplifiers. The Bryston SST2 C–Series is the direct result of this on-going quest, and represents a significant step forward in the art and science of audio amplification. 

PERFORMANCE WITHOUT COMPROMISE With today ’s increased clarity and dynamic range in recordings and movie soundtracks, you need equipment that not only equals, but surpasses, the parameters of the most demanding material available. The SST2 C–Series is without peer in meeting this performance challenge. 

WHAT WE’VE DONE Depending on the specific amplifier model advancements in the SST2 Series include: New power supply transformer design. New push on/off power switch. New chassis design. New Soft-Start Circuit. New Balanced input stage. New Power Supply board Bridging mode performance improvement. Reduced point to point wiring. Reduced circuit board count. Redesinged output chokes. Modular design and separate power supplies for each channel ensure cross-talk is essentially nonexistent, and provide precise and focused soundstaging. Components mount directly into glass-epoxy circuit boards, eliminating variations in signal travel and wire interaction. Reviewers agree: sound quality is improved to a stunning degree, realizing a higher, and far more consistent standard of musical accuracy across a line of amplifiers than ever before possible.


SOLID CONSTRUCTiON Bryston’s research has shown that separate power supplies provide the best imaging, clarity, and dynamic range — all attributes that are especially crucial given the emerging and demanding high resolution digital sources. The power supplies employ multiple filter capacitors per channel, rather than single pairs of larger filter cans, allowing improved high frequency response, and reducing overall losses in the supply. In the 9B SST2, and 6B SST2 models we carry the modular concept further, making the channels removable.

SUPERIOR INGREDIENTS We use only the finest components — such as 0.1% metal-film resistors, polypropylene capacitors, custom-wound toroidal transformers, and hand-matched transistors — to reduce noise and distortion to the absolute minimum. Gold-plated balanced or single-ended (RCA) input connectors are standard as well as gold-plated 5-way loudspeaker binding posts, to eliminate possible causes of distortion from corrosion. As befits products intended for use on stage as well as in the home, the SST2 chassis are extremely robust.

FLEXIBILITY & FEATURES SST2 amplifiers offer feature flexibility. For example, all allow a choice of input connection — balanced XLR-F, balanced 1/4” phone, or single-ended RCA jack — together with a switch to select gain settings. A trigger input allows system-wide on/off control. Overall, the SST2 Series itself facilitates flexibility in putting together the total system through a variety of channel and power output options.

THE RESULT Although the description of circuit innovations can indicate the research and commitment we bring to the design and manufacturing of our products, it’s not the whole story. The purpose of all this technology is to place you within the scene of the movie, or to transport you to the actual musical event. Whether you can experience all the drama, movement, and emotions intended is the one truly meaningful measure of any audio/video system. Take the time to visit your Bryston dealer and audition our SST2 Amplifiers. We think that you’ll rediscover how exciting audio can be.
