I have been an advocate of Signal Wire, such as PC Triple C (CCC as some now refer to it), and D.U.C.C, both made by Japanese Companies. I am also informed that Mitsubishi have created a new generation D.U.C.C. wire.
Either of these two wire types used as Signal Path wire is strongly suggested to be investigated.
Cables will be found of varying values that contain this wire type.
I do not intend to move on from these wire types, but recently commenced looking at other wires used in Cables made in Japan. This led to learning that there is wire in use that has a metallurgy that is creating a Metal Alloy with Copper (Cu) and gold (Au), where the Gold is the infill metal between the Copper crystals in the wire structure.
The world has changed, and there are top-selling cables in Japan not even known about outside of the country. With the Japanese being renowned metallurgists, before committing to any Cable choice, extending a search and inquiry beyond a forum might produce an end sound much improved in attraction over immediately available options being put to use.
Lending cables is a great way to contain costs and learn a lot about an umbilical's impact on an end sound.
The Links will give an alternate impression of my suggested wire types, and are compared in a review to be read. There are more of these wiire type reviews able to found if a search is done in the link info.
