As an audiophile you read alot online, and if there is something that divides the camps it is power cords, and noise filters. So I was very skeptical when ordering this. Now I know. People stating this doesnt have an effect or that it is pure snake oil, either have systems that cant take advantage of this or just havent bothered trying for them selves. Received very fast. 7 days to Denmark. Cleared customs so thats a plus :)
