Some good suggestions above, although I would not personally recommend electrostatic or planar speakers in your rather small room. I'll add only one choice to the mix: a pair of used Vandersteen 2Ce's -- you might even find a pair of used 2Ce Signatures at just over $1k. The Vandies pair very nicely with your McCormack electronics, and will also perform well in a smaller room. If you want a nearly full-range speaker that simply makes great music, you won't find much (maybe any) competition with the 2Ce / 2Ce Signature for around $1k.
