i'd like to use the Fiio E17 both at home and outside home.
At home i'd like to use it connected by optical cable to Asus Xonar U3 usb card (for 7.1 virtualization in games).
Outside home i'm looking for a source that can send digital signal to E17... I don't know if my smartphone (Newman K1, great china phone) will support it, since i've read a lot of phones don't have a enough usb output power.
What can i buy?
Thanks to anyone that will help me!
