Is There A Solid Stereo Reciver To Be Found

[NICK DAL]

I want to puchase 4 polk Lsi9's, and the pinnacle digital 600 sub, BUT I am unable to find a stereo reciver with a sub output..... Do they make a stereo reciever with enough outputs to run 4 bookshelf speakers (polk Lsi9's) and a subwoofer........
