First pic real Foo right hand pair, fake Foo left hand pair. Second pic fake Foo bottom, but a different fake Foo than the first pic. But I also think the top green wire has a Foo connector - real Foo but cheaper. That was made by Paul at RFC and he told me they were Furutech but they aren't current production. Also all use real Foo cable.
Real Foo is definitely these: https://www.futureshop.co.uk/furutec...ctor-pack-of-2
Absurdly expensive but when you take them apart they use a totally different design which is much easier to work with than the fakes.
Note the web page makes no mention of how they lock into place.
There must be some cheap RCAs that work in the same way. I am not sure the OP is up to making his own cables.
I did look quickly on Amazon but didn't see anything obvious.
