For true vinyl fans, a high performance phono pre-amplifier is a must-have to get the best performance from your music. Thankfully, Cambridge Audio has the perfect solution in the shape of the 651P. Adding weight, scale and detail to all your favourite music, our flagship 651P, is a thoroughly reworked and revised replacement for the legendary 640P, which picked-up dozens of awards in its day.

Many of today’s (and yesterday’s!) audio systems, from dedicated stereo amplifiers to all-in-one systems and receivers, lack the specialist, built-in amplification (known as a ‘phono preamp’ or ‘phono stage’) required for the direct connection of turntables. Cambridge Audio’s 651P phono preamplifier, allows virtually all turntables on the market to flourish by using a sophisticated electronic circuit design that has been created to accommodate the two most commonly found types of phono cartridge used with modern turntables: Moving Magnet (MM) and Moving Coil (MC). Designed to bring out the hi-fi realism inherent to vinyl’s grooves, the 651P is one of our most cost-effective, performance-enhancing creations.

The 651P uses advanced amplification circuitry to provide the lowest possible distortion and noise. Compatible with the audiophile’s cartridge choice, Moving Coil, the 651P model also employs high-spec multi-parallel capacitors to achieve exceptional RIAA accuracy. In a further nod towards its audiophile credentials the 651P features a subsonic filter to remove the unwanted and disruptive effects of low-frequency energy. And in line with Cambridge Audio’s commitment to the environment, the new 651P is fitted with a power switch to allow consumption to be zeroed when not in use.
