Lacee - I initially thought the same as you, but I tried the spades on the 10 gauge cable because it was very difficult to install the connector.
The improvement was so noticeable I did the same for the rest of my cables, which resulted in the same improvements.
All of the spade connectors I have used are copper - the plating is very thin and probably does not have much effect on overall resistance. They also more than double the contact surface area, which will halve the overall resistance of the joint.
I've now tried this on both Furutech and DH Labs cables with the same results - a deeper more precise sound stage, improved dynamics and enhanced details.
Bottom line - with the spades I have used, it pays dividends
We all know - not everything in this hobby always makes sense :-)
