Would like to have Hi-res output. Now foobar2000 mobile don't support this as I can see. On Android all audio files are decoded at sample rate 48 000 Hz (Blue light on Dragonfly Red). On iOS all audio files are decoded at sample rate 44 100 Hz (green light on Dragonfly Red).
Other players like USB Audio Player Pro (Android) and Neplayer (iOS) can do this so I guess it would be possible for foobar2000 to fix this issue.
