Details & Highlights

Product Highlights

    Raising the bar and setting industry standards for audio quality, the Cambridge Audio Azur 851W class XD power amplifier elegantly pairs serious power with exceptionally low distortion for pure, crystal clear audio of the highest quality. Taking advantage of the sonic brilliance and purity of a Class A design without overheating, and the efficiency of a Class AB design without sonic limits, Cambridge Audio patented their Class XD technology designed to harness the best of both worlds with all of the advantages and none of the disadvantages. Give your audio system the treatment it deserves – the 851W is perfectly calibrated to flawlessly match other components in the Azur 851 series like the 851E pre–amplifier and 851N network player.

    CLASS XD

    Rather than use a Class A design, which is sonically brilliant but generates vast amounts of heat, or a Class AB design, which is efficient but sonically limited, Cambridge developed their own Class XD amplifier design which the 851W takes advantage of. This has the sonic purity of Class A and the efficiency of Class AB for the best of both worlds. For more information on their unique patented Class XD technology watch the video at the bottom of the page or click here for a full description.

    TERRAPIN BUFFERING

    When designing a stereo system, listeners are often encouraged to think about system matching, where components are handpicked to provide the best overall sound quality. People often assume this is due to the different audio characteristics, but frequently it is due to impedance (the relationship between voltage and current input/output) matching components. Products perform at their optimum when their input and output impedances match. This isn’t always possible though so they decided to develop the unique Terrapin impedance buffering module. This enables the 851W to be paired with a huge variety of audio sources and pre–amplifiers of varying impedance without risking any sacrifice in musicality or overall audio performance.

    POWER AND CONTROL

    To build the 851W to be the best toroidal transformers were essential. But rather than use one for everything we designated one for the sound amplification itself, and another for the input circuitry. This means the signal is unaffected by audio output volume, so always sounds fantastic. The primary toroidal transformer provides unrestricted power to the dual mono amplification blocks. It’s a true audiophile transformer that will operate without distortion and with no buzz, interference or hum. The second smaller toroidal transformer takes care of pre–amplification processes. View the videos below for an insight on why we use toroidal transformers.
