I presume so - it would not work as a tonearm cable without full screening to prevent hum, and these cables patently do not pick up hum. See the description at https://ammonite-audio.co.uk/product...tonearm-cable/ which state "Cores are tightly twisted followed by a mylar/copper drain for excellent EMI/RFI rejection" and that's clarified in the specifications as "Shield: Aluminum mylar with silver coated copper tight pitch spiral"
