I see some Audio Cable brands like Brimar, Toxic,... advertise that the purity of silver used for their cables is 7N. But another famous brand, Double Helix cables keep insisting that 6N silver is the highest purity in the world with reliable evidences from Acrotec. I am quite confused and dont know who to trust. Does anyone have the most reliable evidences about the purity of silver, which indicates that 6N, 7N or 8N does exist or not?

They do exist, and you better buy it from the manufacturer that was patented to make it. I will leave the rest to you to figure out
