For our RCA cables, we apply the same recipes that make our power cables successful. Abrasion and hydrogen peroxide treatment of the sheaths. Use of Teflon PTFE dielectrics and high quality shields such as Mumetal or copper. The outer sheaths are made of basalt or Mylar. And of course we apply a mineral shielding with Shungite powder.
We are happy to offer our cables for a 30-day trial period.
