From a safety perspective, it's important to ground your components.
With that said, you should notice significant improvements by floating/disconnecting the ground from every component.
Grounding has a way of introducing much noise into the AC.
Not sure why, because the typical ground wire is usually connected directly to the neutral bus at the service panel. Since the neutral wire is already connected to your component (opposite the hot wire), as a non-electrical engineer I am perplexed that the ground wire would introduce any ADDITIONAL noise over and above what noise the neutral wire may already contain.
