The 535 of course does not and the 545 version II does. I may buy an original 545 but not if I can't use my Wireworld Polaris cables with spades (not worth the $ to buy the Audioquest adapters or have the Wireworlds re-terminated).
I really don't know the size of the spades. They are on rather large Wireworld Polaris cables. The point is that any type of binding post that is not "five way" will not allow spades of any size to clamp flushly.
