The Bryston 4B3 stereo amplifier, black, features an innovative Quad-complementary topology that achieves minimal distortion and high levels of accuracy and transparency. This cutting-edge design incorporates twelve active devices arranged in a novel layout that ensures compatibility with any preamp while delivering the initial 6dB of gain with utmost precision. The input stage of the 4B3 is meticulously crafted to offer unparalleled transparency, boasting impressively low distortion figures, down to 0.0001%. The amplifier's quad-complementary topology effectively eliminates harsher higher harmonic distortion, resulting in a harmonic response reminiscent of Class A designs but with significantly reduced distortion. Each channel of the 4B3 is powered by its own fully independent power supply, complete with a separate transformer, ensuring reliable and consistent performance. Consistent with Bryston's commitment to quality, the 4B3 is accompanied by a 20-year warranty. It's constructed with no compromise philosophy, reflecting Bryston's dedication to producing top-tier audio equipment.
