Anyone else have Led Zep Remasters I, II, III 96/24 WAV files? How are they playing with your X3? Mine don't work and I've tried everything short of asking HDTracks if I can download them again. FWIW, they played just fine with the previous firmware.
I've tried contacting Fiio support, but haven't heard back from them.
I have them in FLAC and they work fine on the X3, just convert the WAV's to FLAC
