Product Description

Second-Generation Class XD Technology Cambridge Audio's Azur 840W is a high-end power amplifier designed by the same team behind the critically acclaimed 840A. The 840W uses an evolution of Cambridge Audio's hugely innovative Class XD technology for a highly detailed, naturally musical performance. The second generation Class XD is now complemented by a new output stage that has been "Product of the Year" 2008 - The Absolute Sound Magazine carefully adjusted to integrate with this novel technology, along with revised balanced inputs for lower distortion and noise. An awesome power delivery of 200-watts-per-channel at 8 ohms gives excellent load driving ability. Or a truly massive 500-watt bridged mono can be harnessed for driving 'difficult' high-end speakers. At the core of the 840W's strength is a patent pending, Class XD (crossover displacement) technology. This innovation first used in the 840A has been subtly revised following continuing post-launch development and critical evaluation. Uniquely, XD gives pure Class A operation at low levels, moving smoothly into an enhanced version of Class B at higher levels. This system should not be confused with Class AB, which inherently generates greater distortion at high levels than a pure Class B design. XD technology feeds a controlled current into the output stage actively displacing the crossover point in a new way, so that the usual Class B crossover point no longer occurs at zero volume -- the worst possible position in terms of audible distortion -- but at a significant output level. The result is a smooth and linear transition between the two modes of operation, which differs significantly from the abrupt gain transition of a Class AB amplifier. To facilitate this, the Azur 840W amplifier includes a massive, oversized low flux toroidal transformer, incorporating a silicone-steel screen.
