Iconic British Engineering

The QUAD 303 is a legendary Class AB power amplifier that has stood the test of time, renowned for its transparent, musical sound and robust build quality. Originally introduced in the 1960s, it has been meticulously re-engineered to meet modern audiophile standards while preserving its classic charm.

Advanced Output Stage

Featuring QUAD’s signature "Triples" output stage, the 303 employs a fully complementary design that ensures low distortion and high linearity. This innovative approach delivers a clean, precise, and musically warm reproduction, impressing at both low and high volumes.

Flexible Power Options

The amplifier offers versatile power configurations: 50W per channel into 8Ω, 70W per channel into 4Ω, and 140W in bridged mode into 8Ω. This flexibility allows it to drive a wide range of loudspeakers with ease, including QUAD’s electrostatic designs.

Modern Enhancements

The reissued QUAD 303 incorporates a custom 200VA toroidal transformer, upgraded circuitry, and improved thermal management. These enhancements ensure greater reliability, reduced heat generation, and compatibility with contemporary audio systems.

Classic Aesthetic

Retaining its iconic anodized chassis and CNC-routed heat sinks, the QUAD 303 exudes a timeless design that remains relevant in today's hi-fi landscape. Its understated elegance complements any audio setup, from vintage to modern.
