Do pure copper banana plugs make a difference in the quality of the speaker sound.

I was going to paste a picture of the relative connectivity of base metals, as there are some misconceptions.  fortunately, the above post is correct.  The IDEAL combination for banana, spade or what ever you are using is Copper, that could be silver plated.  Im trying to find just copper connectors, with very little luck.  I dont want them gold plated, just copper, and if any plating is used, silver only.  Does anyone have any idea where to get this?  I will not pay 100 dollars for a pair of copper banana plugs that use less than a dollars worth of copper, thats for sure.  Anyone have a good solution?

Thanks!

Roxy54 i totally agree, was just trying to find that.  Im actually looking on Aliexpress now, as they are the only ones that are showing pure copper, NOT gold plated.  im also looking at spade lugs, as i think they may offer more surface area,. not sure yet.
