Future of cables!

Geoffkait, you are a mystic. dlones, I and quite a few others are not and I dare say that we are destined to be much happier in our under ware than you are and much wealthier. This is all old science. Just because you and others do not know about it or understand it does not mean that it does not exist. It is only a fool who trusts his ears only.

Uh OK, mijostyn not sure I understand what you're  getting at but trying knots in cables isn't  science. 

Knot would introduce inductance for common mode signal and no inductance for normal mode (common mode choke), but I doubt that one turn would make any difference.   I would rather put as many turns as possible on large toroidal ferrite core (with high permeability).  IMHO it is waste of time and effort if you don't have noisy power.  On the other hand there is nothing wrong with "placebo effect" if it makes you feel better .  At least it doesn't cost a lot in comparison to other "improvements".

Gee whiz, guys, I thought some clever and curious fellow would at least try the square knot before passing judgment. Too superstitious, I reckon. What are you afraid of? This looks a lot like if it’s not in Wikipedia it’s not real syndrome.

"...trying knots in cables isn't science."

Unless you try some of those sailor's knots. That is an art form of science.
