Increasing volume is their main purpose, however their are fields that can be improved or decrease depending on quality of the amp. Soundstage is a particular area that is changed, width and depth, I have a $100 amp here right now that displays very good depth on the centre channel. Dynamics, bass impact, treble response, a lot these areas are being altered because the IEM is feed more power, and most of all increased Clairty
. The main purpose of an amp is to supply more power without colouring the signal however doing so is not an easy task and an expensive one. Plus an amp will also display different tone levels such as brightness and warmth depending how it's built, people like to pair different amps with a certain source or headphone to create balance, even down to the cables being used. There's many areas that can be covered about amping.
