The Bryston 2.5B3 is a compact stereo amplifier with brand new Quad-complementary topology designed to provide low distortion, accuracy and transparency.

The Bryston 2.5B3 boasts twelve active devices mounted in a groundbreaking array, matching the amplifier to any preamp and providing the first 6dB of gain. The input stage has been designed to offer supreme transparency with distortion figures as low as 0.0001% distortion.

The Quad-complementary topology removes any aggressive higher harmonic distortion and provides a harmonic response similar to Class A designs with far lower distortion. Each channel includes its own fully independent power supply with separate transformer.

Like all Bryston products, the 2.5B3 comes with a 20-year warranty and is built with a no-compromised approach.
