Having read the locked thread, my tuppence worth, being a non believer too, when I dislocated a finger on a geordie who slide tackled me at the park. When I took some homeopathic pills it really improved, the days I didn't it hurt more. Anyway on to the important thing of sound quality, and how on earth can a shielded mains cable not work. It reduces interference, often the block will have surge protection and having a Physics A level I would imagine a cleaner signal actually improves the output. Anyway the truth is in the pudding (yes I know).
