It should be connected in a way which allows the shield (the braid that goes around the signal pair) to perform its function. That function is to make a tunnel-like extension between two chassis inside which the actual signal pair is well-protected (figure 21). That's what "shield" means.

Ano, stínění není klíč k dokonalému kabelu...

Shielding affects sound. Even shielding done the right way acts like an additional capacitor, and creates "dump artifacts" that will audibly change the sound of the system. For this reason, most XLO cables are constructed without shielding. To keep the sonic effect of shielding to an absolute minimum, XLO cables that are shielded*

are insulated with shielding spaced as far as possible from the signal conductors and grounded outside the signal path. Even so, to the critical listener, neutrality may be affected, if only very slightly. XLO recommends that, for systems of the highest resolution, shielding for line level interconnects should not be used unless severe EMI or RFI problems make shielded interconnects necessary. It's generally preferable to deal with, or accept, any shielding affects to annoying hum, noise and static problems that seriously degrade the sound.

Different shielding materials have their greatest efficiency at different frequency ranges. By using two entirely different shielding materials (copper and aluminum), XLO/HT cables offer a broader range of protection from electromagnetic (EMI) and Radio Frequency (RFI) noise and interference.
