Know any good recievers and/or speakers?

So, ive decided on what i need for speakers for my system, i already have bookshelf and floor-standing, but i need a sub, a center and a reciever.

I was planning on these, and yes the sub is a little small but i have had good experience with the brand, and unless the higher model klipsch goes on sale im sticking with it. Any suggestions or w.e. would be great.
