What about grannyring Helix interconnect cables and Helix power cords?

@grannyring thanks for the offer.  I'm winding down on my collection and duplicates myself. Last pair of my own going up for sale now. Maybe someone can take advantage of these unique ICs. 

@grannyring Just so you know I never sold these here on the Gon except for a couple of my personal sets that were extra and lying around. Other than that I only made a couple of these cables for audio friends. I am no longer making cables. Never sold Helix power cords. Great sounding ICs and power cords however!

Hey grannyring,
If you are willing to share and not trying to pull you backwards, when you were making ICs, did you settle on anything you felt was special to your ears in terms of the metallurgy and type of conductor(s) used?
