So the fiio e6 and fiio e11 are pretty cheap on amazon right now and I am tempted to buy an amp.
Now, I heard the iPhone 4s has a pretty good built-in amp itself. And some people state that the momentum don't need to be amplified.
However Im looking for something new, for a new sound to throw at my headphones. I could say I am an average audiophile. I have decent ears.
QUESTION: Is it worth it to buy the E6 with my configuration? What about the E11?
