I cannot believe the arguments phrased here because of a lack of a simple circuit diagram and a bit of simple circuit knowledge.
If you wish to know the difference between a single ended circuit and a differential circuit, AND the relative grounding difference, you need a simple CIRCUIT DIAGRAM and knowledge about how circuits and especially SHIELDED circuits work. The word "ground" should be defined MUCH better for people who are "wire nuts," i.e., those who follow WORDS (OMG!) better than circuit diagrams. de KQ2E
