What about using the Ground Lug on Power Conditioners?

Most power bars designed for HT & component style power conditioners all have a Grounding Lug that gives a common ground for all connected equipment. You just run a cable from your component to the Lug and it's supposed to fix all ground loop problem, you might have to ground all of your equipment I am not sure. Has anyone tried using this? I will be getting the 7700 soon, it will be my first 3-prong plug in my rack and if I hear a hum that is the first thing I am going to try, I have heard bad things about using "cheater plugs" on equipment that was designed with the ground in mind.
