There seems to be some misconception towards what an amp can do. An amp can do a lot more than simply amplify a signal. An amp, depending on it's output impedance, will increase the damping factor on the headphones, basically increasing the grip the amp has on the driver, meaning that the driver would trace out the input signal more accurately. Also, if using a true line out, then the amplifiers slew rate will come into play. This changes according to the model of the opamp. This is the time it takes for an amp to change it's output from it's highest +ve voltage to it's lowest -ve voltage. This maintains the quality of the signal that the headphone is reproducing, meaning that the sound will be less blurred. Think of it as the transient response of an amplifier. There is more to it so if anyone wants, they can read the case study I wrote on solid-state amplification for my Higher Technological Studies:
