If you guys are getting better sound from lifting the grounds, there's a reason for it - something is up with your AC. Lifting the ground is a band-aid solution, not really a wise move - better to fix the root of the problem than half-assed things like cheater plugs. I have used those in the past but don't any more. A good power conditioner (ideally a balanced power setup, like Monster HTPS 7000 or Equitech 1.5Q or 2Q) should cure most of those things, if not all of them.
Good tip on redoing the main house ground - I will probably do that soon. Sean, thanks for the info on Coax seal. Looks like good stuff.
