Cambridge Audio has been at
the forefront of British hi-fi for more than thirty five years. Since its inception
in 1968, Cambridge Audio has brought some of the most innovative and technologically
advanced products to market.
During the ‘70s, the P40, P50 and P110 amplifiers established
the international reputation of the Cambridge Audio brand. The ‘80s saw
Cambridge Audio launch the world’s first two-box CD player. In the ‘90s,
the DacMagic was the first product in the company’s history to win an
esteemed What Hi-Fi? Sound and Vision Best Buy award. The new Millennium saw
Cambridge Audio continue to innovate with its award winning DAB digital tuners
and of course the highly-acclaimed Azur range.
Cambridge Audio has a philosophy of using only the finest quality
components, all models are developed using state-of-the-art test and measurement
equipment and feature the latest technology. This commitment to engineering
excellence, combined with state of the art manufacturing facilities, means every
Cambridge Audio product offers the best possible performance. Prior to launch,
all designs undergo rigorous evaluation involving meticulous listening and fine
tuning.
But the main reason for Cambridge Audio's success... our people.
We employ nearly 80 colleagues, the majority at our London headquarters, including
over 20 engineers in a dedicated research and development facility. Every member
of our team shares the same passion for hi-fi and home cinema as you –
our customers. That’s why we always go the extra mile to make sure we
only produce products we're proud enough to take home – and trust us we
do!
Cambridge Audio products are distributed in over 45 countries
and the company turns over in excess of $40 million.
