851W (S)
(Receivers and Amplifiers - Amplifier)

The Azur 851W improves over its already highly respected predecessors in just about every way. At its heart is Cambridge Audio's innovative and proprietary Class XD system, with 12 output transistors per channel. Combining the best of Class A and Class AB and removing the downsides of both, Class XD amplification eliminates crossover distortion like a Class A amp, while offering the power efficiency of Class AB.
