I have gotten great results on my Vandersteens using the old Music Meter solid core wire, which seems to provide a nice balance between crisp solid lows, and clean highs. Music Meter is out of business. There is a company called Clear Day Cables making solid core wire, both copper and silver. I haven't tried their cables, but they get good user reviews, and they are pretty inexpensive, but then a lot of cable is ridiculously expensive. Plus they make sets that are made up for biwireing.
As far as the spade/banana plugs go yes, you can take the screws out of the speaker inputs and stick the banana plugs in. I just upgraded to 2Ce Sigs from 2Ce, which is a significant upgrade, and am inputting with banana plugs. Viva Vandersteens.
