Yes. Ground is floated at the balanced outputs. Which is why I originally thought I needed to use a transformer, in the way that you mention which is to ground one side of the secondary while taking the SE signal off the other side. But what bothers me about that strategy is, I think, that a transformer will isolate the balanced outputs from DC ground. Do I have to worry about AC ground?
