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 it

Introduction

Capable of delivering an enormous 120 watts of high-quality power, it benefits from two audiophile-grade mains 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.

Specification

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.

Our casework is more than just an exercise in great design, too. The full-metal chassis is acoustically damped for greater performance, with a striking yet robust brushed-metal fascia.
