Cords do make a difference. I had a Sony dvp9000es in my system and had a buzzing coming from the speakers with low volume. I could hear the noise when listening to classical music. I went over the musicdirect and picked up a new cord for about $200. The buzz was gone,the music was not lacking anything, and I was happy. This is with a dedicated outlet. I do belive cords in general are a hit and miss kind of thing.
