Speaker upgrade to go with new Arcam AVR 600?

I am in the process of upgrading my home theater. Replaced my Onkyo 605 with the Arcam AVR 600. Have Paradigm V5 monitors right now,pair of titans,cc 290,and a pair of mini monitors that I use as surrounds. I want to do floorstanders this time. I am mainly a tv/blu ray watcher,do some videogaming on my PS3. Very little listening to music.I have no problem at all purchasing used speakers.Just trying to get an idea what I should go and take a listen to.
