From a sound point of view, I can recommend this Klei RCA plug copper silverplated. Low mass principle adds hardly any capacity to the cable. Unfortunately, you have to be careful when soldering as it doesn't release a lot of heat. It is best to plug it into a used cinch socket and solder it to prevent the contacts from deforming.View attachment 117276

Thank you, but I am not looking for connectors. I am happy Cardas can install a connector which contains no rhodium.
