Furutech spades on copper cables


I want to make DIY speaker cables.
I have Furutech copper-silver-copper-rhodium plated spades, that I'm planning to terminate copper multistrand wire with.
Speaker binding posts are WBT 0710 Ag (Silver).
My question is- would terminating copper wire with this particular connector, vs. the gold-plated one, be a problem?
Is there any rule of thumb with regards to matching cable material with the material used on speaker binding posts (Silver with silver, or copper with copper), or with the material, used on the cable connectors?
Thanks
