No matter what Powercord will be used, all of them have upgrade plugs. The Plugs have in general an improved contact area and I think, this is one of the real advantages. You can try those with the existing Power Cord and I think, you will get an improvement, too. I bought those from Oyaide, internally they are really good. I use some of their Tunami cords, they are a real serious solution (technically and from the material inside), shielded and safe.
