I bought it last Friday. So far it does what it says, nothing drastic, minimal coloring and quite transparent. to be
fair I have read it sounds better after some burn in time, I will give it that chance and post an update.
Settings: EQ/Bass 2, gain low (though gain high sounds more detailed at times), high voltage.
Using iPod touch 4g, fiio L9 LOD, fiio E11, UF-T10. Through the iPod music player and Equalizer app.
The E11 is taped to the back of the touch with thick heavy strength double side tape (this is new for me, finding it better than rubber bands or velcro).
I do believe my Royal Cmoy has more detail and depth (although It could be the coloring).
