The Bryston 28B Cubed is our flagship power amplifier, a single channel (mono) amplifier which 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.
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 Cubed as 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 28BSST² 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 Cubed 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 Cubed virtually perfect freedom from overload on any type of speaker or music, bringing the performance and realism directly into your listening environment. The 28BSST²’s ability to resolve subtle musical details has to be heard to be believed – it truly sets a new standard : Mission accomplished.

REVIEWS:

"If you want a really high-powered amplifier, there’s really no need to ‘compare the market’ before taking the not-inconsiderable plunge: Bryston’s 28B SST² monoblocs are the amplifiers you should buy. Simples!" - Chris Croft, Australian HiFi

"The performance of Bryston’s 28B SST² on Newport Test Labs’ test bench was outstandingly good: it returned results that are amongst the best I have ever seen for any amplifier, and absolutely the best I have seen from a high-power amplifier. Awesomely
awesome!" - Steve Holding, Australian HiFi
