Cambridge Audio DacMagic Plus

This DAC/preamp from Cambridge offers a wide variety of connectivity and usability in a well built and great priced package! Twin DACs isolate circuitry and improve sound quality by allowing each channel to operate independently, drastically lowering the noise floor and increasing dynamics and resolution.


DacMagic Plus
Digital to Analogue Converter & Preamplifier

The DacMagic Plus has fantastic new features including wireless device connectivity and stunning audio performance from music of all formats. Thanks to twin DACs it instantly improves audio fidelity from all your favourite digital products allowing you to make your computer, TV, Blu-ray player and other devices a true part of your hi-fi system.

The DacMagic Plus works by taking a direct digital audio signal from your computer, TV or other device - bypassing their built-in digital to analogue converters. This signal is then carefully analysed and upgraded using our ATF2 upsampling system. Once this process is complete, the DacMagic Plus outputs your music as a much purer analogue signal straight 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. Watch the video above to find out why our proprietary ATF2 upsampling technology makes such a difference to the sound produced by our DACs.

By linking our 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.
