You can buy Belden from Tech America. Everyone that attempts to build this cable, please note the following: Do not consider constructing the cat5 cable with more than 8 pairs of conductors, this is critical to the wires' performance. These conductors are very small (24 gauge), but the 8 pair conductor design is the best of any variations.(Many people think that a good cable needs to have lots and lots of copper, so they try bundle 12,16 and even 20 pairs of conductors. Unfortunately, these configurations sound pretty awful). When you hear how good the bass and dynamics are with the 8 conductor pair configuration, you will scratch your head to why many commercially available cables are so damn big and heavy. Additionally, the wires need a minimum of 80 hours of break-in before you make any serious comparisons with other cables.
