I have some problems with the X3.
I started to use WMA Professional (please, no comments about its inferiority/uselessness/etc., I use it to conserve storage space) in 24/96. Files are encoded with 440 kBit/s CBR, 2-pass. They pose some problems with the FiiO. Playing them, it sometimes crashes (not on the same files).
Behaviour is always like this: X3 is starting to play one of these files, switches its display off (I configured it to 30 seconds) and when I then press a button the FiiO doesn´t react anymore. It´ll play the song to its end though, after that it simply stops playback but stays switched on (I can remove the headphone and can still hear the click of the relay, as though the FiiO is 'thinking' that it still is playing back). The solution to this problem always is a reset. This is not very convenient.
Another thing: those 24/96 WMA Professional files are decoded as 16/96. 24/48 WMA Professional files are however decoded as 24/48. Doesn´t make sense to me.
I would be glad if these problems could be solved as WMA Professional is a well sounding lossy HiRes format which conserves lots of storage space compared to FLAC or APE.
