Integrated Class XD Amplifier

Our flagship integrated amplifier delivers power, finesse and astonishingly low distortion!

2 Year Exchange Warranty

Quite literally in a class of its own, the new 851A Class XD integrated amplifier is designed to offer power, finesse and astonishingly low distortion. At its heart lies our own proprietary Class XD technology, which has been refined and enhanced since its inception in the 840 series, allowing even greater musical detail to be delivered to your speakers

Stunning performance, ease of use and incredible value.

Capable of delivering an enormous 120 watts of high-quality power, it benefits from two audiophile-grade toroidal transformers: one for the sensitive preamp section and one for the power stages allowing the 851A to deliver its immense output without stress. This incredible speaker-taming amount of power can be precision-controlled with another innovation found in the 851A - the new fully balanced silicon gate volume control, which gives very fine adjustment across the volume range and highly accurate channel-balancing.

Because everyone's needs are different, the 851A offers two main types of connectivity: the more commonly found RCA/Phono inputs, plus two pairs of fully balanced XLR connections. Our matching 851C upsampling CD player also features both types of connection, allowing you to connect your system in the very highest quality possible.

Speaking of flexibility, you can even control your iPhone, iPad or iPod using the 851 Series remote control when they're docked in our matching iD100 digital dock.

Unlike many high end amplifiers which excel in one area over another, we believe the 851A offers the perfect combination of high performance, flexibility and ease of use. It's designed to take your listening experience to an entirely different level and we invite you to audition our best amplifier to date at your nearest Cambridge Audio specialist.
