JFTR if you know what you're doing a ground lift could be a temporarily
solution, e.g. the power supply of the Brauner VM1 tube microphone has
got a ground lift through a capacitor. However, if a ground lift is
needed, something is fishy and using a ground lift potentially is
dangerous to life. _But_ even professional gear sometimes provides a
ground lift.
