    As one of the few devices that includes a DAC and can bypass the Apple DAC, this is an affordable option to get CD quality output from your Apple device.

    The Nuforce Icon iDo Function

    Apple uses its own audio codec, Apple Lossless Encoder (ALE), to compress and store music files on its devices in original CD quality without loss. However, even ALE files only sound as good as the default DAC (digital-to-analog converter) found within the mobile digital device. Icon iDo bypasses the built-in DAC and extracts the audio data stored on the device in its original digital form in USB Host Mode. It then converts the high-quality files for bit-perfect and low-jitter music playback.

    Icon iDo also offers a built-in headphone amplifier capable of powering power-hungry headsets, giving users a total audio experience. By properly powering headphones, Icon iDo enhances the auditory performance of the headphones because optimal amperage is being delivered to them, allowing for greater audio clarity.

    Realize your music's full potential

    If you've never heard your digital music played through a high-quality DAC or headphone amp, you're in for a big treat. You'll get sparkling clear highs, detailed midrange, and deep, sonorous bass you can feel all the way down to your tailbone. Every instrument and vocal stands out clearly and crisply.
