From the manufacturer:
"This high-quality Digital Audio Converter (DAC) delivers upgraded sound to any USB compatible computer. The USB DAC is ideal when used to bypass the low-grade internal sound card in your computer, adding a higher fidelity to your digital music library. Included with this DAC is a unique music player software package incorporating Direct Streaming Technology which outputs an exact bit-copy of the original source by resampling the Kernel Mixer of your PC. The software is compatible with Windows®, MacOS® and Linux® operating systems. Power is supplied to the USB Box via the USB port."
