Well since other manufacturers are advertising here let me say the following: I can terminate to any length of Belden 8718 or 8720 which are twisted pair shielded 14AWG or 12 AWG for one whole lot less than 620.00 per pair. In fact my typical price is under 120.00. I use gold plated banana plugs.
And all this time I thought this was what manufacturer forums were for, pity the fool!
