In Reply to: So if I wanted to "float" the grounds on my system... posted by clio09 on August 29, 2008 at 07:34:08:
Many systems are plugged into a power strip, which is plugged into an outlet. If you plug some three-wire audio components into a power strip, then float the power strip by using a cheater plug at the wall outlet, you will still have ground loops in your system. The individual power cords will have their safety-earth conductors connected together in the power strip. You may experience a reduction in noise (see my essay "Noise and distortion" in a thread above), from disconnecting the system from the house wiring AC safety-earth, but this arrangement will still pick up local noise.
To fully experiment with "floating the grounds," you need to make sure the individual component safety-earth wires are all disconnected, from each other as well as the house AC wiring. This is at your own risk.
