Gmood1 -- the +100 db spl simply allows you (or should) lots of headroom using little energy. Useful for dynamics!
It doesn't mean that you're obliged to listen at 1W average! BUT, if there is a transient in the programme matl that requires 30db headroom (I am dreaming, I know... oh well) it's very easy to achieve for someone who listens at an "average level" of ~70 -- all you need is amplification reserves in excess of 1W!
