Hey all. New to the forums, so forgive me if this has already been answered. I am looking for a higher fidelity audio setup than earbuds with my iPhone. I was doing some research and found out that the way to circumvent the shoddy sound from the iPhone's audio jack is to use a direct line out from the 30-pin dock connector, and direct that into a DAC/portable amp. I was thinking something along the lines of the Fiio E7 (http://www.amazon.com/gp/product/B0...=1789&creative=390957&creativeASIN=B003E6K1VK) paired with the ATH-M50's (http://www.amazon.com/gp/product/B0...=1789&creative=390957&creativeASIN=B000ULAP4U). I was wondering if any of you have tried this or a similar setup and what you thought of it. Do you think it's worth it for the price? Thanks so much for all the help.
