I've had my E17 for about a year now and I refuse to listen to music without it.
Does the e18 have EQ? if not then it's a no contest, E17 all the way. Although the samsung galaxy has a pretty damn good EQ. soooooo????????
I have Keff in ear and over ear headphones. they are a bit much on the high end for my taste so it's nice to give them a base boost. The in ear has a slightly different sound so I like having the choice. My E17 is falling apart so I am now in the market for a new mobile DAC.
My main listening source is my ipod classic with a LOD cable.
Does the Fiio even have a competitor at this price range? Seems like no one else has a viable option under $150.
