Description
The ultimate in amplification and built without compromise, the 851 is our finest integrated amplifier. It possesses incredible power, finesse and astonishingly low distortion. In its design we assessed every component for sonic excellence and revised, reviewed and optimised the signal path for minimal distortion. Thousands of hours were spent testing and tweaking, the result is an amplifier like you’ve never heard before.
We built the 851A without sonic compromise, and that’s true of the connectivity too. Nine RCA inputs cater for regular analogue inputs, while for high end components there are two sets of balanced XLR inputs. We’ve added a pre-out for connecting to a subwoofer or power amp, while two sets of speaker terminals allow for bi-wiring or running additional speakers in a second location. Finally, Control Bus inputs allow the linking of compatible Cambridge Audio products for easy control from one remote.
