Bubblepnp vs Zidoo player

[qguy]

Does the Zidoo zx9 - optical to MF M1 Dac have an advantage over locally stored files on android phone with Bubblepnp to Wiim pro - coaxial to MF M1 dac?

Don't see how. Either way you should be getting bit perfect playback up to the DAC, assuming the source files are the same. If you're getting any kind of noise due to a ground loop or what have you, the electrical isolation provided by the optical cable might be an advantage.
