Bryston 3B³
Bryston 3B³ stereo power amplifier, designed for audio/video systems requiring medium to high power without compromising sound accuracy.
Description
The Bryston 3B³ is a two-channel power amplifier, designed to equip audio/video systems requiring medium to high power. It is a dedicated amplification stage, intended to be paired with a preamplifier or a source already fitted with a built-in preamplifier, in a stereo configuration.
Bryston designed this model for installations where power must never come at the expense of sound accuracy. The manufacturer's stated aim is to provide sufficient power reserve to drive demanding speakers, while maintaining faithful signal reproduction over time.
Long-term reliability is one of the design priorities of this amplifier. Bryston aims for stable operation over time, a point particularly relevant for a unit intended to remain in service for an extended period within the same installation.
This type of amplifier is aimed at hi-fi enthusiasts and audio/video installations seeking a stereo power stage capable of driving current-hungry speakers, without any degradation in sound quality as volume or load increases.
What to check before buying used
On this Bryston power amplifier, it is advisable to check the operation of both channels at high volume to rule out any hiss, hum or imbalance indicative of ageing capacitors. The gain potentiometer should be turned through its full range to detect any crackling or excessive play. A visual check of the heat sink and input/output connectors also helps identify any sign of overheating or oxidation.
