This is pretty exciting. A portable with dual Wolfson dacs and versatile voltage supply. While hooked up to the USB the amp section will be running at a little under 5 volts but when on the 9 volt battery you will be running at the 9 volts.
Run time is around 9 hours for a 300mA battery and I would guess around 15 hours for an alkaline or a 500mA LiPoly.
