I'm seeing a lot of comments that cables don't affect performance. Any educated audiovisualphile, audiovisual enthusiast, or electrician should disagree with these comments, to a point. There are many, many cheap (as opposed to inexpensive) online and retail cable / wire products that are built with such low quality, impure copper, if even copper, and built so poorly that the result is a significant amount of resistance, which certainly does have an effect on the both sound and picture quality--especially if you've long runs. Now, between cables such as Radio Shack Gold Series, Canare, Belden, Transparent, etc., I can stomach the argument that there is virtually no difference in performance (durability is an entirely different subject). But make no mistake, there are sneaky cable and wiring manufacturers out there that cut enough corners to make a product that, without question, will affect performance.
