Adding shielding to existing cables


So I have some interconnects that are picking up all sorts of RFi. I know this for two reasons, one, as I move them around the noisy/buzz sound changes, and two, when I switch them out for shielded interconnects the noise goes away.

so, I bought some tinned copper shielding and some new RCA plugs. I’m going to cut the existing RCA plugs off the existing cable and install the new shielding and new plugs. The thing is the new plugs have a plastic body so there is nowhere to easily connect the shielding to ground.

I was thinking of running a pigtail from the shielding and attachIng an eyelet to ground it to my preamp since there is a grounding lug. Would this work or is there a better way given what I intend to use?

Not to muddy the water but I'm considering the following advice from DIY blogger, Steve Reese. Steve has compelling ideas for making one's own speaker wires, ICs and power cables.

Any thoughts, anyone, on Steve's reasoning?

Hi Steve.
You left out how your practical research is supported by PS Audio research and other "mad scientists" (respectful and admirable context used here) and endorsements of other fellow DIYer who simply wonder and tinker leading to improvements in audio, many theory on induction and capacitance found thanks to great minds at Bell, Westinghouse, RCA, and Western Electric, and other's, many who’s research is lost on those who think they are smarter and don’t value the vast knowledge of past great minds.

Oh, well.

From imagination comes opportunities.

BTW. Cardas has a nice article on audio cables:

Just stumbled across John Darko’s recent vlog on experts vs neophyte view points that has relevance to this thread. Maybe.

Are you a "conspiracy theorist in an audio world?"

As John Darko recommends, I'll listen to the experts first before I lean on my own understanding!

Steve, you mention "skin effect" in the following page on Helix structure for speaker wire or ICs.
I have read that skin effect is a component of AC current, not DC. How is it a challenge here?

Thanks guys. I guess I need to find an audio primer. Is there an Audio For Dummies?🤔

I was under the mistaken belief that speaker terminals and whatnot labelled positive and negative meant DC. 😶
