    I will be able to show you that you can measure the difference when direction is reversed. These stranded, twisted pair cables are twisted in a certain direction, and following the right hand rule, when you put two wires in close proximity, when the twist is in opposite direction, you can change the balance of inductance and capacitance. Also, you will notice when you take these cables apart that the orange, green, brown, blue wires inside have different twists.......

    I understand about the twist direction but failing that are you saying there is a directionality to all cables

    There are different configurations and types of Cat5. But Cat5e is specified as stranded, and unshielded.
    Interesting. I'm looking at a box right now, with the label by the manufacturer stating Cat5e, and solid core. Differences between different parts of the world?

    No - the ones without a twist, like your Valhalla speaker cables should not be directional. Solid-core cables that are not twisted should also not be directional. I don't believe in the"crystal boundary" explanation to cable directionality. However, all stranded cables have the strands inside each cable twisted, and most of these turn out to be directional. You can make them non-directional by making a cable with four conductors. Use two conductors per +ve and -ve and have one in each direction..... but then it will sound different.

    By the end of this dialectic, you may WANT to believe that cables make no difference because of the nightmare cables can be!!

    That's interesting.... but you could just as well use whatever you have because solid-core/stranded will make very little difference for this exercise.

    It's also really funny on the Pro side all of the people that dismiss cables until you name all the big engineers that use them. You can hear crickets chirp after that.

    Certainly not Transparent or MIT. I have an equal helping of Mogami Gold, Canare, JPS, Monster and custom cable made by Redco
