Amplifier 擴音機 / Cambridge Audio / DacMagic Plus
DacMagic Plus

Digital to Analogue Converter

Introduction

Improving on a legend is never easy, but Cambridge Audio has gone back to the drawing board to create the DacMagic Plus with exciting new features, wireless device connectivity, and best of all, significantly enhanced audio performance.

We live in a world of immense musical opportunity. Computers, TVs and Blu-ray players can all deliver audio to your hi-fi system, but because they’re primarily designed to perform other functions, their audio outputs lack quality. But by simply connecting them to DacMagic Plus, you can bypass their inbuilt digital to analogue converters transforming their humdrum performance into something altogether more spectacular!
