is my room small for a pair of B&W 802's

My listening room is a dedicated listening room 18.6 by 14.5 I would like to put a pair of B&W 802's in but I am worried it would be over kill for the room. I will drive them with a pair of Mcintosh MC501's or Classe mono 400's. Am I too big for the room? Also what amp would you think is best suited for these beasties. Pass Labs, Classe, Mcintosh, or Bryston. Solid state only.
Thanks for your time and insight,
Eric
