   That's one way of looking at it. The other way of looking at   
   it is that when you know the relationship between full scale   
   and output level or input sensitivity, dBFS has a physical   
   meaning. However, it's more useful to specify a voltage (dBu   
   etc.) than dBFS when working with actual useful digital   
   audio hardware.   
      
   I've been trying to find out what the original poster's real   
   question is, but he seems to either not be sure or just   
   refuses to answer, rather enjoying saying "no, that's not   
   it" rather than formulate a question that isn't abstract.
