That is a large room for the Vandy 2's, I would consider getting the 3a sigs-at the least, with the 2w/wq subs. or the Quattros used.
If you are set with the 2's, then get a pair of Vandy subs. For a room that size, you are going to need some bass augmentation.
For amps/preamps/DAC, I recommend McCormack, which pair nicely with Vandersteen's and don't cost an arm and a leg.
I would also contact Johnny R at Audioconnection, he is a Agon member, and a Vandy Dealer, and he won't steer you wrong.
