High Quality Digital Cables

I m not sure where the belief that you had to have the top of the line cables to make your computer or home entertainment system run at its peak levels. Perhaps it is a hold over from analog days, where cable quality really did matter. For digital streams of data, there is very little, if any, benefit to buying top of the line cables. A digital signal only had two possible states, on and off. As long as the system understands the current bit, it makes no difference if the cable was five bucks or five hundred. The quality of the bits going through the cable makes no difference.
