The 851 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 we’re incredibly proud of.
"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."
- EUROPEAN IMAGING & SOUND ASSOCIATION, AUGUST 2012
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.
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
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
