The metal on the binding post should match the metal of the connector.
Mate gold spades to gold binding posts.


Why?


I expect he's thinking of the 'fretting corrosion' that you get when mating
tin and gold plated header pin type connectors for example. The tin rubs off
onto the gold, oxidises and the contact goes high resistance eventually. You
don't get this problem with tin to tin or gold plate to gold plate.

Never heard of it being an issue with binding posts though.
