I would get them unterminated. They will then easily accommodate the Vandersteen's. The binding posts on the NAD shouldn't be a problem either. The wire gauge is 12awg. Past posts recommended unterminated as the best sounding too.
Personally, they weren't a good match on my Vandersteens. They are very revealing but it was a case of too much because I'm using Class D amps (Channel Islands D200's)
