Hi again,Jon wrote:
>>>If you try the FFRC design, I urge you to properly terminate it by using the wire pairings rather than just connecting the whole run of wires in each jacket together. This will lower inductance, and reduce the effect of the jacket material as a dielectric. Wiring it as indicated in the TNT article will maximize the amount of dielectric involvement of the jackets, which may not be made of a good material if you don't get the Plenum grade CAT5 cables.<<<
Jon, please note that the Cable is actually designed for Bi-Wiring and that the Tweeter section (where it matters) is wired in pairings, and only the Woofer-connection uses the wires per jacket.
This was done to reduce (very succesfully) the Capacitance of the cable to neccesary minimum. Many solid-state "HiFi" and "High-End" Amplifiers I have come across have poor stability into capacitive loads, hence this compromise.
If your Amplifier will be stable into capacitive loads, go with Jon's recommendation.
As for Jon's comments on the makeup of the Cables, I completely agree with his comments. As the "common" insulation for Cat 5 in Europe is polyolefin (and not PVC) I extraplolated that that would be the case everywhere.
As this is not the case, PLEASE use Plenum rated Cat 5 UNSHIELDED Cable only.
