Audiophile power cords vs. the cables in your walls

[Kingrex]

Peter,
Can you confirm if DDK Ching Cheng's are copper or tinned copper wire?

Mine are tinned copper.

Mine are tinned copper.

Did you get them from DDK?

Yes

I have some I bought from ddk. One that I cut to directly connect to a distribution box, it’s all copper. Mine is definitely not tinned. I want to say it looked a little oxidized too… I’m not using it anymore illl try to find it and get pictures.

I will look at mine again. I though it was tinned. I have a bunch of those type cords so I may have lost track of which are DDK.

The ones that are about nine feet long with clear molded male end.

Just took out the C19 plug that I fitted to one of mine - it is also copper. Fortunately it does not look oxidized ...

The ones I got from DDK had both clear and black male end. He told me they were the same cable. Both have the green dot, so they are certified for hospital use. Measured capacitance between wires is around 210 pF, 1.4 microhenry short circuit inductance according to my records. Those are typical values for similar gauge common good quality cheap power cables. Audiophile cables can vary between much lower or much higher capacitance.
