Product Details

Cambridge Audio Azur 650A Black Integrated Amplifier, Model CAMB650AB

The new Azur 650A focuses on our most closely guarded principles – explosive sonic performance, incredible value and timeless design. Whatever music you’re into, we guarantee we’ve invested all our passion into making the very most of it.

Cambridge Audio’s 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.

If you demand the most from an amplifier, then look no further than the 650A. 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.

Making the 650A a true benchmark in its category was of course a key requirement to Cambridge Audio’s design team.
