Tinkerboard and Dacberry One

The OSO DACBerry One is claimed to work with the ASUS Tinkerboard. Question: If this is true, would the DACBerry One be an upgrade to the audio that is already included in the Tinkerboard? Would the SPDIF out on the DACBerry One outperform that on the Tinkerboard? Or is the Tinkerboard on its own, or through an IFI Purifier, all one needs?
