Unless you are somewhat close to a 60 degree angle, say 50-70, your sound stage is probably pretty screwed up anyway. Sure narrower gives a better defined center image, and wider can give you more stage width while making the center fuzzy, and that is all personal preference, but I am giving you the benefit of the doubt. 1/3 of 1/2 of 60 = 10 degrees. Easy peasy.
Again, Occam's razor. You are trying to assign special properties, outside what is possible, to stranded wire. The reasonable thing to do is look at what is more likely. You are misinterpreting, you are biased, or something is broken. Stop getting all incensed, step back, and think about what is really happening and why. Getting angry at me is not going to change your listening, though it may reinforce or break a bias. I lean towards the former.
