V.A.C. avatar speaker recommendation?

I have a Avatar integrated amplifier, and I am looking for speaker options. I want to keep the price down, say less than $2500.  The room is 11 x 13 with a vault of 11 feet joining a room for 13 x 17 x 11 with 2 adjoining hall ways into a kitchen and bedroom areas. I have Madrigal wire throughout with lots of pictures on the wall as well as CD cabinets
 ( one each side of the room) and albums against the walls. This price point includes new and used speakers. If you have experience with this integrated, PLEASE chime in. Thanks
