Cambridge Audio 540P-B Phono Preamp - Black Review

Cambridge Audio 540P-B Phono Preamp - Black Feature

• Moving Magnet Phono Preamp
• Active RIAA Equalization

Extending the functionality of Cambridge Audio's critically acclaimed integrated stereo Azur amplifiers and AV receivers is the 540P phono preamp. Employing state of the art circuitry and high grade components the 540P is a high quality Moving Magnet (MM) phono stage. This model features 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.

Cambridge Audio 640P Phono Pre-Amplifier Silver Feature

• Gain @ 1kHz: 39dB / 55dB
• Superior amplification circuitry for its MM and MC stages to provide the lowest possible distortion and noise
• Multi-parallel capacitors to achieve exceptional RIAA accuracy
• Acoustically damped steel chassis
• External power supply

The Cambridge Audio 640P phono stage pre-amplifier uses superior amplification circuitry for its MM and MC stages to provide the lowest possible distortion and noise. In addition, the flagship model employs multi-parallel capacitors to achieve exceptional RIAA accuracy of only 0.3dB up to 50kHz and features a defeatable subsonic filter. The Azur 640P phono pre-amplifier employs a comprehensively specified Moving Magnet stage, as well as the higher gain needed for compatibility with high-end Moving Coil (MC) cartridges. This raft of technologies combines to offer a hugely dynamic, involving and open sound. The 640P features the now customary Azur acoustically damped steel chassis and a robust anodized aluminum front plate.

• Moving Magnet and Moving Coil operation
• Passive RIAA EQ for minimal phase shift
• Subsonic Filter

Extending the functionality of Cambridge Audio's critically acclaimed integrated stereo Azur amplifiers and AV receivers it the 640P phono preamp. The 640P features a highly specified moving magnet stage, as well as the higher gain needed for compatibility with high-end Moving Coil (MC) cartridges. This model features 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. Tthe 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.
