Cambridge Audio is a British hi-fi manufacturer founded as a division of Cambridge Consultants in 1968 by talented young technology graduates including Gordon Edge and Peter Lee. Their first product, the revolutionary P40 integrated amplifier (2×20W), made history as the first amplifier to use a toroidal transformer, which became standard in high-end amplifiers. In 1994, Cambridge Audio was acquired by Audio Partnership, owned by Julian Richer and James Johnson-Flint of Richer Sounds, and is now solely owned by Johnson-Flint. Operating from London and Cambridge with a 30-strong team, the company focuses on what they call the 'Great British Sound' with annual turnover exceeding £33 million. Cambridge Audio specializes in premium audio equipment including wireless headphones, streaming systems, integrated amplifiers, CD players, and high-end hi-fi components, maintaining their reputation for innovative engineering and accessible high-quality audio reproduction after over 50 years of British audio excellence.
