There is definitely a "right way" to do this, and in many systems the
improvement is huge when all plugs in the system are correctly
oriented. Many years ago I used a small pen-like device measuring the
electric field from the components. The smaller indication from the
"pen" was the correct way t

I haven't tried it but its certainly possible. One of the significant
contributors to ground loop noise issues is the leakage current through
the power supply (there are ALWAYS leakage currents, they are in the
microamp range but they are still there). Very few power supplies are
completely symmet
