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?

@scroydon - Thanks for that update on the other "mad scientists". I don’t feel so isolated :-)

I was not actually aware of the contribution from PS Audio and all the other great minds in the companies you mention - but I am not surprised that it gets lost with the glut of information AND more importantly MIS-information available on the web today

Most of my "knowledge" came from tinkering, the tinkering of other DIYer’s around the globe and Keith Louie Eichman, who got me started on all of this with his cable topology.

Once I got into the geometry of cables I started looking at what was out there from companies like Kimber Kable, Cardas, AntiCables Gutwire and most recently Inakustik.

The latest revelation has been the impact of Dielectric Content of the insulation on wires and thanks to companies like VH Audio there is a broader selection of great wires (copper and silver both with AirLok insulation) to choose from. Chris, of VH Audio is also a well known DIYer that I have a lot of respect for and he makes some very good cables.

Bur sometimes it does seems those with the "loudest voice" wins the day.

However it is refreshing to see some pretty clever cable designs coming to market of late.- i.e. for those audiophiles that prefer NOT to dabble in DIY

Regards - Steve

Tell a lie long enough and loud enough and it will become "the truth."

"Mass opinion is the work of the Devil."

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?"

Any time I've tried shielded and non shielded varieties of even the same cable....shielded always sounds "closed in" in comparison.

I have ditched mega-dollar cables in my system for williewonka DIY Helix design cables and love them; I can tell you from listening and evaluating over 20+ brands of cables with some retailing for $5K, this DIY Helix beats them all with a build cost of $200...

All of my signal cables are the DIY Helix Typology and Steve has offered the audiophile community a world-class cable at an entry level price which is quite amazing IMHO.

No need to knock it if you haven’t tried it and for $200...
