 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. Specifications:Max.
