I'd make own with OCC wire and 4 mm banana jacks.
Tinned wire will probably make a better connection than them pins.
Cable Troubleshooting
I've got an issue with my Apature Accuflow cables. The banana plugs that go into the speakers are fine, but not into my mid eighties Denon receiver, as the ports are too small to fit the thick cable. I'm wondering if these will solve the problem.
TIA
