PondrrWoah. That's a bit much. Their spec sheets are nowhere close. While I love FiiO and are waiting to see the X7, neither the X3 or X5 version 2s could pair close to the specs on the L5. If we are comparing direct hardware, all the chips are superior on the L5.
As for software, that is something that should be left open because I love the UI of the L5 but dislike the X3 and X5.
ZilventI'm always skeptical of people claiming that "the chips are superior" in one gadget over another. Did you arrive at this conclusion based on any real evidence (ie. a double blind listening test)?
zoomorphI'm Agree with you.
I think Use RMAA or AP devices and show the results of measures are far better way to PR
