For all the hype of the expensive AC cables, it’s amazing what they do NOT list in the properties of the copper they use. OFC is the popular boast, but they don’t mention Ohno Continuous Cast or annealed forging to eliminate grain and the boundaries present in "cold" drawn wire which add noise and distortion. The brand I use to make AC cables offers cable made from these processes. I know I am using better copper than what is used in more expensive, completed cables. If they had grain-free copper in their cables, they would talk about it. Please tell me who does, and at what cost. Use good plugs and Total Contact, which no big company uses, and you have a world-class AC cable for < $1K.
