Galaxy S3 phone and external DAC

I want to find something like the Dragonfly DAC, or something similar, to work with my Android based Galaxy S3 phone. I would like to play the music stored on the phone into my main system but with better sound than what comes out of its mini jack. All files are stored either WAV or MP3,

Audioquest confirmed that the Dragonfly will not work on an Android operating system. Someone pointed me here but I don't have any clue about the sound quality (is it really any better than the analogue out mini jack on the phone?) Seems too good to be true for such low cost - HIFIMEDIY SABRE.

Then there's this on Amazon - DiiO E18 Kunlun?
