P500

OWNERS CERTIFICATE

Dear Cambridge Audio Owner,

Thank you for purchasing this P500 Power Amplifier.

At Cambridge Audio we are dedicated to the
manufacture of quality audio products of the highest
possible value. Coupled with its perfect partner, the
C500 Control Amplifier, your P500 is capable of true
hi-end performance without the inflated price tag
normally associated with hi-end equipment. We have
achieved this by careful design, thorough attention to
detail, streamlined production techniques and by
listening to our customers. We are grateful that you
have selected this product and would welcome any
comments that you may have.

The P500 design adheres to the principles of true hi-fi,
with a dedicated high current dual stabilised power
supply, resulting in an amplifier with a staggering price
performance ratio. Signal paths within the amplifier are
all as short as possible and the topology is fully optimised
to give a great sound stage and dynamic freely flowing
sound.

The P500’s maximum output power of 55 watts rms
into 6

Ω, is capable of delivering generous amounts of

current, allowing it to drive a wide range of speakers
and sound a lot more powerful than its specification
might suggest. Inclusions such as a custom designed
tight-wind low-flux toroidal transformer, metal film
resistors, multiple audio grade capacitors and a high
efficiency custom heatsink further reinforce this
amplifier’s audiophile identity.

No corners have been cut concerning build quality, with
the amplifier’s solid aluminium facia not only providing
a classy finish, but also contributing to overall chassis
rigidity.

On behalf of Cambridge Audio, may I wish you many
happy years of listening pleasure!

James Johnson-Flint
Chairman
