CAMBRIDGE DACMAGIC PLUS/B

In more detail

The DacMagic Plus works by taking a direct digital audio signal from your computer, TV or other device - bypassing its inbuilt digital to analogue converters.

This signal is then carefully analysed and upgraded using our clever ATF2 upsampling system. Once this complex but instant process is complete, DacMagic Plus then outputs your music as a much purer, lifelike analogue signal to your amplifier.

Custom developed by our dedicated team in the heart of London, DacMagic Plus is totally flexible and supports digital music of all formats. It even allows you to upgrade 24-bit music files stored on your PC for better-than-CD performance from your digital music collection.
