Re: AC and signal cable of whatever type
I think this whole "don't leave your cable on your metal spool" is hocus pocus. Seems to me that most actual work in a balanced audio connection comes from the transformers or active electronics at each end, canceling out the extra noise picked up along the way, and much less about the twist in the cable... I'm sure the twist helps some, but anything near what the cmr stuff does.
I did my 2 years at electrical tech school, and one thing I know is that the neutral and ground wires help reduce the EMI in the regular 120v cable, as well as provide current return path and safety ground. If you put a clamp on ammeter around a hot and ground or hot and neutral, it reads 0. I'm thinking that inside the cat-5 wiring scheme that there is also some form of "balancing" system to reduce the cables EMI output, and this also prevents this from acting a pure wire wrapped on a spool, acting like a choke. I think the whole "I got a burst of static out of my system" thing should be addressed by someone from KT or Behringher as to in what possible weird condition could that possibly happen! There was only one person stating this as a problem, as far as I know, and he's working on setting up to use a different cable (so it might have been a bad connection or cable anyway). I doubt we need to worry about pulling all the cable off or coiling the cable weird for the gig's we do. Sorry for the rant, but that's what forums do best, eh?
Sorry I thought you were in Austrailia, Dan.
