Shielded silver interconnects

I am currently using Nordost SPM's. In my new home I am having problems with unwanted EMI. Any suggestions for comparable shielded cables?

Help appreciated.

I believe the issue has to do with ground loop.
Ground your preamp properly would help even more.
The chord signature cables are amazing, HIFI plus product of the year. they are sheilded and they have built in grounding clips (can be removed if unwanted)
The Pure Note Paragon is a very quiet cable, blackest background I have yet to hear. Worth your audition.
