Twisted pairs are effective at reducing interference from magnetic fields. Cable shielding is effective at reducing interference from electric fields. So the lack of twists at the end will increase susceptibility to magnetic fields and the lack of a grounded, metallic connector will increase susceptibility to electric fields.
Thanks Mojo,
By mentioning magnetic fields in the same paragraph as electrical fields, it sparked me into finally understanding what you are trying to say. Even though you said the word "electrical" several times, my brain was apparently stuck in magnetic mode.
A good demonstration of the danger in being a technical jack of all trades but master of none.
