To be fair, James (Fiio) has been very upfront about the less-than-stellar build quality of the X3:
now I have nothing to worry because Chinese customer is the most picky customer. now they are very satisfy with the sound quality and the features . the only thing I am not so satisfy is X3 is designed
in 3 years ago so the build quality and appearance does not reach our new level ( E12, E17 )。
anyway, there are not any DAPs can compete with X3 in the music format support. even the expensive one.
Very sorry, lots of head-fi'er known that X3 is designed before E17, the build quality of X3 is not as good as E17, but the SQ is better than E17.
although we have the ability to make a more better X3 in build quality, but the time is not enough , also the cost will increase too. hope you can understand. but for X5 , it will represent our best ID in 2013.
