Please add support for FiiO DAPs (Devices). My device is the FiiO X7MKII.
(Unfortunately) running Android 5.1.1, seems to be close to stock with some added features.
This device is definitely capable of having 24 bit playback, as shown under “File Format Support” here. Also, the device’s stock music player provides 24 bit out.
