Hi. Is it possible for you to buy both of them and try it? That's what I have done. I bought E17 and then BioScienceGeeks cMoy Amp. I chose the cMoy because I prefer the sound of it (more natural sounding to my ears) compared to FIIO where in the treble seems to be a little bit excited (to my ears).
