CXA80 - 80W Integrated Amplifier

 

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.

SOUND QUALITY

Nothing prepares you for the sound quality of our 851A. Rated at 120 Watts per channel and built with a fastidious attention to detail, it presents your music with astounding depth and incredible clarity. The precision volume control provides remarkable stereo separation, while the overall effect is to give your music collection a new lease of life.

CONNECTIVITY

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.
 

 

 

CLASS XD + TWO TRANSFORMERS

Rather than use Class A or Class AB amplifier designs, we developed a novel and unique new design called Class XD, which combines the sonic purity of Class A and the efficiency of Class AB for the best possible result. For more info on this patented technology click here.

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. While a second, smaller toroidal transformer takes care of pre-amplification processes. For more information on toroidal transformers and why we use them view the videos below.
 

PRECISION VOLUME

The precision volume control of the 851A is superbly accurate and marshals remarkable stereo separation thanks to the MAS integrated circuit volume.

ALWAYS PROTECTED

For peace of mind our CAP5 – 5 point protection system means you can be safe in the knowledge that no matter what limits you try and test your system to, the 851A, is fully protected. For more information on this unique development have a watch of the video below.
