If tinning bare wire before connecting to a post is an acceptable
practice, and tinned copper is a better conductor than gold
plated copper; then why wouldn't tinned copper spades be
preferred over gold plated copper spades for terminal
connectors?

Do people really like spending 20USD per 4 connector
spades? 20USD will buy about 100 tinned copper
spades from an electrical mail order company.

I don't see the justification for buying the gold plated
spades. Someone please give me a TECHNICAL
explanation!

Thanks,
Mike

Tinned copper is NOT a better conductor than gold plated copper.
Depending upon how the plating was done, the tin may be more durable.

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