The Quad 303 is a highly regarded British solid-state power amplifier, originally manufactured between 1967 and 1985. It was designed to complement the Quad 33 preamplifier and was particularly well-suited for driving Quad's electrostatic loudspeakers. Its distinctive vertical "oil-can" chassis design contributed to its unique aesthetic.

This amplifier is celebrated for its sound quality, often described as having a smooth, warm midrange and a relaxed presentation that can evoke the character of vintage valve amplifiers. This sonic signature is known for being fatigue-free, making it suitable for extended listening sessions.

The Quad 303 incorporated a pioneering "symmetrical triples" output stage. This design feature was engineered to prevent thermal runaway and significantly reduce distortion, contributing to its reliable performance and acclaimed audio fidelity. The original design was recognised for its innovation and visual appeal, receiving an industrial design award and being featured in a prominent modern art museum.
