Parasound or Anthem 5 channel amp

I'm going to be purchasing a 5 channel amp for my expanding home theater.  The amp will be powering the side surrounds, a pair of height (in ceiling) speakers and my center channel.  Debating whether to go Parasound or the Anthem.  The rest of my system has either a dedicated 2 channel amp or mono blocks (my front mains).
My original semi-informed opinion is that other than the center channel, which is very important, it may not make much difference.  Appreciate your opinions.
