Floorstandings to go w/ Peachtree Nova 300?

I will be selling my PS Audio Sprout and buying a Peachtree Nova 300. I currently use the very good and very inexpensive ELAC B5, but also have about $1500k to spend on better speakers. My room is 16 ft by 14 ft and I am thinking in moving to floorstanding ones. Also, I listen mainly to classical music and jazz.

Any suggestions would be greatly appreciated!
