I'm upgrading my IEM from UE SuperFi 5 to a pair of Shure SE425. My search for higher music quality from my Iphone lead me to wanting some form of amp to further improve the sound quality.
My question is, which one? I'm lost. I listen to music 5-7 hours a day, in a typical office. I want something small and portable. An EQ of some form would be nice as the reviews I have read indicate the 425's can be flat.
Currently thinking of ordering the Fiio E6 and L3. Is there a better option? Will I notice a difference in sound quality?
