So I think I cleared up the confusion on the cables thing. If I buy a Chord Mojo and then I have a Fiio X3 coming eventually.. then I would use a USB micro B to USB Micro B (OTG) cable and nothing else? That would transport the digital from Fiio X3 to the Chord Mojo correctly? EDIT: I Just noticed this On the top of the bottom left picture is something that says coax/line out? Does that mean it is digital coax or analog coaxial? Now I'm even more confused.
