I don't know where this new "quad" thing started, but, when you use two conductors in parallel for a single signal you are absolutley killing your high frequencies as well as adding substantial signal phaseing. You are creating a serious capacitor. If you use this for a balanced signal (2 signal lines) you are doubling the killing. Two twisted wires at both ends are by definition a capacitor (two conductors seperated by an insulator). The resistance of the twised together signal wires cut the resistance in half. Therefore, you now have no idea short of doing the math of where you are signal phaseing and where the high freq rolloff will occur. Hey, just my 2 cents worth, I only use a single wire for a single signal.
