Explain what is a clean power amplifier?


Can someone explain what makes and define what a clean power amplifier is or does?  I have googled and searched the forum and haven't found a simple explanation to grasp. 

Thanks

Here is an ideal amp (100% perfection):

1) zero distortion.
2) zero noise.
3) No phase shift at any frequency.
4) Perfect square wave response.
5) Instant and unlimited current source.

The above is a 'clean' amplifier.  Everyone tries to achieve it, some come close.....
