Best used speaker under $1000 for tube low watter

what speakers would you pick for a tube 15 watt amp. for a small room (14x14), and primarily for classical/chamber, and a little jazz. i would rather take the used route, even vintage, it's always nice to be able to resell without losing much. i can't stand that big loss when buying new. also, the room is oddly shaped with sloped ceilings, the only spot for the speakers is about 2 feet from the wall, i prefer speakers that are easy for placement. any suggestions?
