I’ve always wondered why geometry in speaker cables is so important if they sound better un-shielded. Isn’t the geometry suppose to suppress interference from RFI? Wouldn’t shielding do the same thing?The basic geometry in cables and the basic twist (double helix) is not broken and really doesn’t need to be messed with, it is used everywhere in professional environments. The many complex geometries and materials introduced by high-end cable manufacturers are used to alter the sound and to set that company apart from everyone else in the cable game. It also helps marketing a lot when you have something different to sell, everyone can’t be selling the same basic twisted pair design. If I remember correctly, adding shielding (outer copper braid) to the length of a speaker cable increases capacitance significantly which is why it's not done.
