Audio Partnership

It has its home in the heart of London and remains fiercely independent.

Audio Partnership's products since 1994 include stereo amplifiers, CD players, digital-to-analogue (DAC) converters (namely the DACMagic and ISOMagic series), tuners (both analogue and digital), loudspeakers, subwoofers and cables.

Most recently, Audio Partnership has concentrated its efforts on the Cambridge Audio brand, with an emphasis on products for music playback, from wireless headphones to high-end hi-fi.

In 2011, it developed the proprietary StreamMagic hardware and software platform that is used across the company's range of music streamers, streaming amplifiers and wireless streaming speakers.

Although the company is based in the UK, its products are manufactured in China to take advantage of lower labour costs.
