Maybe this just goes to a personal preference or something. But I have always been shown and told that high quality interconnects will make or break your system. For instance look to home audio and you will find wire that costs 5,000 dollars a meter. I am sure that there is a reason for this. I mean power cords costing 2400 dollars that need a burn in time must be better then using a 19.99 cord you get from radio shack. I am getting what your saying. In most systems running any wire will be fine, because wire is wire or something...but I am still going to disagree. I work for a high purity metals factory (
