Joop Snel from Hilversum, the Netherlands (translated by JvP) -

After plugging in the SNS-Plug nearby my audio system, I felt the impact was just too strong. I started to experiment, plugging it in everywhere in the house, I read that a central heating system can pollute the mains and indeed, there it was, the best place for the SNS-Plug. Thinking again about causes of interference with the mains, I also placed one near my PC. I clearly experience more calmness in the sound now, without any coloration.
