Fun read, however the writer talks about reading reviews by people and you should find out for yourself why should I believe him? Seems like he is promoting exactly what he tells you not to.

Still, ask people who actually own the thing and they will tell you that there is nothing better in a portable amp.
Again more useless information that doesnt pertain to this thread.

On the usefulness of a portable amp, I can guarantee you that you will feel a difference. I do not own the Shure you intend to use nor its impedance but the portable amps seem to provide a bit more power to the sound than my Iphone4 and add in warmth and headstage.
For hard to power headphones like my AKG Q701, the E-11 amp need to be maxed out to deliver correctly while the sound lose most appeal on the Iphone unamped.
Overall, yes, a portable amp is a sound choice if you intend to use high end headphones and a necessary choice if you use headphones with low output and high impedance.
Since I only own two and from the same manufacturer, I will not say that FiiO provides the best products. What I can say is that I am fully satisfied with the FiiO E11. Note that it is better to connect it from the Apple connection than the headphone output. An adapter is necessary.
I am also curious of the opinion of other users about other brands.
