I'd go with XLO or Kimber wires(whichever you can afford). You can order them from www.percyaudio.com bulk and unterminated(you're not going to believe how cheap and great can wires be including interconnects as well) To my knowlege of Vandys they will less-likely benefit from bi-wiring. In this case I suggest threading through the binding posts bare wires(pay less for unterminated speaker ends and get actually more than you think).
However they will benefit from biamping if you consider taking Plinius 8200P matching poweramp thus adding more power bandwidth of the class A operation.
