Product Details

Cambridge Audio Azur 840W Class XD Silver Power Amplifier, Model CAMB840WSIL

The 840W is a high-end power amplifier that has been designed by the same team behind the 840A and 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 carefully adjusted to integrate with this novel technology, revised balanced inputs for lower distortion and noise. An awesome 200W @ 8 Ohms gives excellent load driving ability or, a truly massive 500W bridged mono can be harnessed for even ‘difficult’ high-end speakers.
