PURE PROCESS
The DacMagic Plus works by taking a direct digital audio signal from your computer, TV, or another device – bypassing their built-in digital-to-analog converters. This signal is then carefully analyzed and upgraded using our ATF2 upsampling system. Once this process is complete, the DacMagic Plus outputs your music as a much purer analog signal straight to your amplifier.

Custom developed by Cambridge Audio’s dedicated team in the heart of London, DacMagic Plus is 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. Watch the video above to find out why our proprietary ATF2 upsampling technology makes such a difference to the sound produced by our DACs.

WIRELESS CONNECTIVITY
By linking Cambridge Audio’s plug-and-play BT100 wireless audio receiver to the DacMagic Plus, you can also stream music wirelessly from your smartphone, tablet, laptop, or any gadget that supports Bluetooth*. Additionally, if your device supports the superior aptX CODEC Bluetooth encoding, you can stream lossless CD-quality music from your device to the DacMagic Plus.
*Optional BT100 audio receiver required

ADDITIONAL SERVICES
As well as controlling and playing music that’s stored on your computer or smartphone, streaming services like Spotify and Last FM can be shared with your hi-fi in stunning quality.
