Cambridge Audio AZUR 851A Integrated Amplifier
Nothing prepares you for the sound quality of the AZUR 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.
Cambridge Audio has 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. Included is 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, Cambridge Audio 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.
POWER AND CONTROL
Thanks to numerous improvements and upgrades – and thanks to an overspecified toroidal transformer – the CXA81 delivers a prodigious 80 watts of power per channel. This means the CXA81 has complete authority over even the most demanding speakers, it means big dynamic shifts in music are handled with total control, and it means the whole musical picture is available no matter if you’re playing at discreet background levels or at party-time volumes.
“A MUSCULAR AMP THAT GRIPS THE SPEAKERS AND SERVES UP TIGHT, POWERFUL AND EXTENDED BASS…. CUTTING-EDGE TECHNOLOGY FOR SUBSTANTIALLY LESS THAN HIGH-END PRICES.”
