Would I get any benefit if I were to hook up a FIIO E17 portable amp to my Cowon Z2 player. I primarily use Flac's on my Cowon Device. Also could I do any damage to either device or my headphones if I were to do so?
I own a FII0 E17 and a Z2. Both are great products. But you only need the FIIO if you are using over 300 ohms headphones. I use it with my AKG Q701. For my sure 215 it is not necessary.
