Following a storm I had to replace my Realcable strip that feeds my HIFI. I opted for the Oehlbach17020 somewhat randomly and without much hope that it would change something in her, just to have protection against lightning. After plugging paying attention to the phase, good surprise. After four days of listening (I feared the placebo effect) I must admit that this jack to a real impact on sound quality. In short I have more fish on my speakers I have a marked improvement in sound quality.
