I just made a set with these,
FP-108(R) PCOCC Central PIN RCA Plug Rhodium Plated 9.3mm
They are very well made using an OCC copper pin with Rhodium, and they have a set screw to hold the cable plus set screw terminations for the wire. Furutech offers others that allow solder termination. I cannot speak to the other brands, but in a week or so of play these have opened up very nicely.
