Extending the functionality of Cambridge Audio's critically acclaimed integrated stereo Azur amplifiers and AV receivers are two phono preamps.  Employing state of the art circuitry and high grade components the 540P is a high quality Moving Magnet (MM) phono stage, while the 640P features a more highly specified moving magnet stage, as well as the higher gain needed for compatibility with high-end Moving Coil (MC) cartridges.

These models feature single ended "class A" gain stages and use discrete transistors instead of the more common integrated circuits.  This gives less crosstalk and interference across the signal path, with both designs delivering high gain and linearity.  The 540P employs an active RIAA equalization circuit while the 640P uses passive audiophile RIAA eq, the optimum type for phono stages thanks to its complete lack of phase error.

The 640P also uses superior amplification circuitry for its MM and MC stages to provide the lowest possible distortion and noise. In addition, this flagship model employs multi-parallel capacitors to achieve exceptional RIAA accuracy of +/- .3dB up to 50 kHz.  It also features a defeatable subsonic filter.  This combination of technologies offer a hugely dynamic, involving and open sound.

Both units feature the familiar Azur acoustically damped steel chassis and solid anodized aluminum front plate.  The rear panel benefits from gold plated input connectors to minimize signal interference and reduce connector surface degradation.  A separate power supply is standard on both models.
