Tinning bare copper wire is good practice,

plated copper;

It isn't.

then why wouldn't tinned copper spades be
preferred over gold plated copper spades

There are some concerns about gold plating because it tends to be too thin
to take much wear.

Do people really like spending 20USD per 4 connector spades?

Nope, never done it.

20USD will buy about 100 tinned copper
spades from an electrical mail order company.

Works for me.

I don't see the justification for buying the gold plated
spades.

Ever hear of audio jewelry?

Someone please give me a TECHNICAL explanation!

There really isn't one.

That's odd: the latest bulletin from Tweak Central? prefers bare wire.

Consider the source.

However, the "technical" explanation is gold is good because it
doesn't corrode like copper does.

Bare copper wire corrodes pretty easily and rapidly. Note what happens to
bare copper roofs.

...and tinned wire is someplace in between bare copper and gold, depending on
the thickness of the gold.
