540P
Extending the functionality of Cambridge Audio’s critically acclaimed
integrated stereo Azur amplifiers and AV receivers are two phono pre-
amplifiers. The entry-level 540P is a high quality Moving Magnet design
featuring single-ended ‘Class A’ gain stages and a discrete transistor
input stage instead of the more common integrated circuits. The 540P
employs a highly accurate active RIAA equalisation system. The rear panel
benefits from gold plated input connectors to minimise signal path
interference and reduce surface degradation. An external power supply
comes as standard.
640P
The 640P also uses superior amplification circuitry for its MM and MC
stages with multiple paralleled discrete transistors to provide the lowest
possible distortion and noise. In addition, the flagship model employs
multi-parallel capacitors and close tolerance metal film resistors to
achieve exceptional RIAA accuracy of only 0.3dB up to 50kHz and
features a defeatable subsonic filter. The 640P 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.
Both units feature the now customary Azur steel chassis and a robust
anodised aluminium front plate.
