Essentially we are seeing the start of FiiO entering in the DAP world. When the X5 was released they were still working out major bugs on the X3. The 2 band EQ code I suspect is leftover from the X3 as they literally we're learning as they go and I'm sure a lot of the leftovers were not cleaned up. Too bad because it has potential to be very customizable considering how simple the layout and controls are.
