I am waiting from France too
Take from FiiO Facebook :
FiiO Stock's running a bit dry, yes. We're making a minor revision to the unit before continuing production. New revision will have a new PC DAC setting that allows charging and DAC'ing from the same USB socket, in addition to the current smartphone DAC setting that draws no power.
FiiO The new revision will ship internationally on the 15th. No, we won't exchange old for new as there is no defect on the old units. The only difference between the two revisions is that the old revision requires a separate USB adapter / port for charging the device while using it as DAC. However this dedicated charging port (which also exists on the new revision) charges the device faster than charging through the data connection as on the new revision.
