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.





The answer would seem obvious.  Does the Denon use "pin" connectors?  By a set of adapters that arer returnable if they don't work for you.  

I'd make own with OCC wire and 4 mm banana jacks.

Tinned wire will probably make a better connection than them pins.

Find the right connectors and put them on your cables.  Don't add extra connections to the signal path.
