I tested it both ways and I couldn't hear a difference (but my ears are 62 years old - I can't hear much above 10K). It was suggested that with the finishes tied (hot and ground from the starts, closest to magnets) that there would be more noise if you touch a magnet. But I didn't find that when I tested it.Thanks. This is exactly what I was talking about.
It seems like it could (should?) make a difference - but I couldn't hear it.
