The FiiO E17 can work with Android phones without external power feeding USB:
. FiiO E17 & HTC One:
stock HTC One > digital USB audio out >> USB OTG cable >> FiiO E17 USB DAC >> FiiO E12 amp
. FiiO & Sony Xperia Z:
stock Xperia Z > digital USB audio out >> USB OTG cable >> FiiO E17 USB DAC/amp
. FiiO & Samsung Galaxy S3:
stock Galaxy S3 + USB Audio Recorder PRO app > digital USB audio out >> USB OTG cable >> FiiO E17 USB DAC/amp
Others Android phones can also work with the FiiO E17; do "Search This Thread" "Android phones and USB DACs".
The USB Audio Recorder PRO player can play 24/96 music file, and forward a 24/96 PCM stream to a 24/96 FiiO E17:
