holmz thank you for your time and expert explanations it is appreciated.
I often read about this amp or that has good headroom. I thought it meant that at loud levels when you are pushing your amp to its limit and the music pushes it over its max it has a reserve that can cover that brief moment of sound without clipping. Now I think it means having enough watts to cover any musical note played at volumes up to and including those which will make your ears bleed before the amp will clip. In short, your ears will clip before the amp.
