The Reason of cancel the external power adapter and use USB powered. Many devices (e.g. Computer TV DVD) USB ports output stable voltage and current, And filter some bad waves. So the DAC( Digital to Analog audio converter) will work better, And the decode will be more stable. 2. In addition, Use USB output power that is more environmentally friendly, reduce costs, And compatible with all countries.
