Is it possible to share (a segment) of the fie so we can all play the same file? This narrows the source of hiss down to whether it's a sensitive IEM thing or a specific device/batch issue.
Having said that, I'm certain that the hiss is not from my music files. The same level of hiss can be detected when music starts playing. The hiss remains when I pause the song, or when the DX50 is idling after starting up. Only hiss at phone out. Doesn't hiss when I connect to line out directly.
