analysis for 100w ciruit

[mr_byte31]

Hi all
I found this ciruit on the net
most people say that it works very fine and with a good quality
here is the main link : http://europa.spaceports.com/~fishbake/amp/ca100.htm
I attached ciruit with transistors so it can be easily seen
I made simulation to it and it seems great
i want to make analysis to it so i can modify it
I have a little problem with it
in the positive peak the power is 113 watt and the negative peak the power is 111 watt
I think it will not be noticed but I am seeking to solve this
any suggestions for analysis and my problem
