Cambridge Audio Azur 650A review


The 650A is a worthwhile upgrade to Cambridge's excellent 640A. Partner it with the right equipment and you won't be disappointed

Extensive spec ; burly build ; sturdy finish ; detailed, open sound

Sounds clinical ; lively treble

Unbeatable for scale and insight, but the 650A sounds just slightly detached

Product Specifications

Cambridge Audios highly-respected amplifier topology goes to new levels of performance and refinement with the introduction of the 650A. A completely redesigned output stage helps improve bass response and dynamics even further while enabling control of virtually any speaker with aplomb. Building on the impressive specification of the 550A, the even higher specification 650A leaves many high-end hi-fi competitors behind thanks to separate transformer taps for the left and right channels, twin rectifiers and separate power supplies for dual-mono operation of the left and right power amplifiers. It also features a larger transformer and heatsink; essential to keep it cool with so much power on board! The net result of these critical upgrades is a pure 75 watts (at 8 Ohms) of smooth unruffled performance. But power is nothing without control and its not just at high volumes where this amplifier offer peak performance. A completely new high specification Alps volume pot control ensures perfect channel balance at low levels and is complemented with new tone controls offering equally intricate level setting. Other important improvements include new audiophile grade polypropylene signal capacitors, gold-plated speaker outputs, custom-made electrolytic capacitors in critical positions and several new carefully calculated circuit tweaks. With so much shoehorned inside, its astonishing how the new Azur 650A looks so elegant. In addition to a raft of sonic and environmental benefits, the new Azur range has a completely fresh contoured look with razor sharp displays and velvety smooth controls. A substantial brushed aluminium front panel, a seamless wrap-over lid assembly and dual-layer damped feet all adhere to Cambridge Audios rock-solid design standards and also help improve performance through superb resonance control
