Quad 303 duo amplifiers

Quad 303 amplifier

The QUAD 303, paired with the 33 preamp, has been an iconic hi-fi duo since 1967, renowned for its performance and reliability. Revisited, the 303 retains its robust “industrial” design, with RCA/XLR connections and a mono bridged mode. Its technology, faithful to Peter Walker's original “triple balanced” circuit but with a fully complementary output stage, reduces distortion and improves stability. Offering 50W stereo (or 140-170W mono bridged), the new 303 delivers a refined, full sound, with rich timbres and natural musicality, surpassing its predecessor in definition and subtlety. A real favorite, for use with the 33 or other symmetrical preamps.
