There is no such thing as an AC power ground lift. The correct term, and
please don't take it personally, is _criminal_ _incompetence_.
Calling it anything else should be avoided, because that makes it sound
like something clever which the pros do. Rest assured, they don't.
You _always_ want your case grounded, unless you have double insulation,
and in that case, your power plug is two-pin only to begin with.
Any artist I catch on any stage I manage with tape across their ground
connectors can clock off early, with no show.
The only responsible and reasonable thing to do is a _signal_ ground
lift. Period.
