I think I understand your question. I'll give it a shot.
The power rating on receivers can get confusing.
Alan has a great read: http://www.axiomaudio.com/archives/power.html

Also, it depends on what receivers that are being compared.
Some are better than others. I'm not an expert on the workings of an amp. I believe Alan posted this topic before, I just don't know where it's at.
