Cambridge – Azur 851W Power Amp

Cambridge Audio Azur 851W Power Amplifier Enormous Power: Azur 851W Delivers 200WPC into 8 Ohms in Stereo or Whopping 500WPC in Bridged Mono Configuration Proprietary Class XD Amplification and Separate High-End Toroidal Transformers Anchor Azur 851W, Make it Best-Sounding Power Amp in Cambridge Audio’s Renowned History Power. And plenty of it. It’s what first comes to mind when discussing Cambridge Audio’s flagship Azur 851W, a sublimely accurate two-channel power amplifier that takes command while flawlessly driving your speakers and produces transparent, engaging, and excitingly dynamic sound. Azur 851W offers a massive 200WPC into 8 ohms in stereo configuration and a head-spinning 500WPC when run in bridged mono configuration. No matter whether you use one or a pair, Azur 851W impresses with knockout sound that is hands-down the finest to ever come out of a Cambridge Audio product. And that’s no small praise. Azur 851W is based around 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 eliminates crossover distortion like a Class A amp while offering the power efficiency of Class AB. This superb component also uses separate high-end toroidal transformers: one for the power amplifier itself and one for input and other circuitry for performance unaffected by audio output volume or dynamics. Proprietary Terrapin impedance buffering modules separate amplifier and signal impedance for consistent sound across sources. And Cambridge Audio’s CAP5 protection prevents against DC spikes, overheating, short circuits, and clipping. To complement the outstanding increases in stereo separation and imaging rendered by the Terrapin modules, an all-metal chassis provides massive structural rigidity, damping elements, and acoustic-resonance control. Inside and out, Azur 851W is built to serve for
