Cambridge Audio Azur 840C
CD Player
The 840C is the crown on Cambridge Audio’s hugely applauded Azur CD player series. Like all Azur products, the 840C also shows an unprecedented performance level and skill in its price class. But instead of reconfirming the expectation pattern on entry level, the arena that Cambridge Audio is generally associated with, they are now about to compete in the medium price segment. The 840C has many technologies developed by Cambridge Audio, such as: ATF™ (Adaptive Time Filtering) and asynchronous upsampling, developed in cooperation with Anagram Technologies from Switzerland. This system very cleverly interpolates the 16-bit/44.1kHz CD signal to 24-bit/384kHz by using a 32-bit “Analog Devices Black Fin” digital signal converter. The signals achieved in this way are fed to two 24-bit/384kHz d/a converters of the same manufacturer, in double differential set-up. For a perfect channel separation, each converter takes care of one channel, and in order to obtain a distortion that is as low as possible, the converters operate fully differentially.
