I watch a ton of movies and my wife watches tv and Netflix. So I just purchased 2 RP280-F's, center RP-450C., SVS PB Sub and running on Marantz 7013. I have 4 def tech speakers in my ceiling. I am still within the time period to return the equipment and upgrade. I was thinking about going crazy and getting the RC 64ciii. I was told that I would have to upgrade all the Klipsch speakers. Is that true? Was trying to figure out if it is worth the money? Thank everyone in advance for their advice.
