biwiring is a debatable tweak. Most people say it makes no difference, and I agree. But since speaker wire is cheap and the owner's manual does imply that biwiring is somehow better with these speakers, I would probably go ahead and do it for the cheap price of speaker wire.

I do like spades because the tightness of the connection is determined by how tight you screw down the terminals and how tight you crimp it, but I think a good banana plug is as good and more convenient (by good I mean the ones that are very tight). But then again, just bare speaker wire is also good if you don't need the convenience as there are just fewer connections involved
