Sorry if this is answered in previous threads, I am new here so I do not yet have permission to use the search function.

New question about power cables: There is a lot of discussion online about the effect of shielded power cables. The cables from GR Research are not shielded. Does this mean that shielding is not as important as some people think, or is the braid of the individual strands just as good at disabling signal interference from the outside?

When it comes to A/C power, the noise is already on the lines. It has been picked up by the miles and miles of cabling.

What you want is not to shield the first few feet of the cable, but to use it as a filter.

Thanks. I will try your power cables .

Can you extrapolate on this because as stated it makes no sense to me. Not trying to be rude, but there is also EMI & RFI that permeates the area and could possibly "infect" the cable. Also how is it that a cable without a shield becomes a filter? Thanks.

The braided geometry of the cable acts like a faraday cage, which restricts the transmission of EMI & RFI, making the cable more capacitive than inductive, and restricting that signal being applied to the cable itself.

Danny did a demonstration of using different speaker cables as radio antenna.
And the more heavily braided the cable was, the less of an antenna it becomes.

I'd imagine the same property that affects external EMI/RFI applies to the flow of electrons internally as well. Tho I don't really understand it well enough myself to explain the how/why in any real depth.
