The specification for the project says 'improved sound quality', I think improved is defined as higher distortion as the amplifier can't improve sound quality of the original audio source it can only make it louder.

The specification of the amplifier is that it should:
Provide an improved sound quality over the un-amplified output of the MP3 player.
Have an input impedance of at...
