Your player and the Portable Micro Headphone Amp in its standard configuration together with a Micro Strap and Micro Bag creates an outstanding personal audio system that provides hours of high-end portable listening pleasure wherever you may roam. Add the optional internal Digital to Analog Converter (DAC) and the Portable Micro will accept optical and coaxial S/PDIF digital inputs, or USB input from your computer. You'll be amazed at how good your laptop or PC computer can sound when the audio digital-to-analog conversion process is done properly, and outside the noisy electrical environment ever-present inside your hard-drive.
