I have Paradigm Studio 100's for the main. Monitor 11's for the rear and Monitor 9's for the sides, I also have PSB 2200 sub. I know that I should use the Reference Studio CC for the center channel, however I can buy the LCR-450 for about $350 less. May I use this for a center channel with this sytem? What are the difference in specs on the two and will it suffice? Thank you.
