Newbie question for amps: Sunfire, Anthem, Rotel?

Hey everybody. I am just starting to get into my system. I have an HT setup with Paradigm Studio V.3 (40's, 20's, CC 470, and sub). Still working on breaking speakers in.

I am looking for a good 5 channel amp (170 Watt+) to drive them. Currently I am powering them by an older Denon AVR. I have looked into the Sunfire Cinema Grand, Rotel 1095 and the Anthem MCA 50. All have gotten sound reviews and seem to hold their value, but won't break my wallet or piss my wife off too much.

Any suggestions? Any other amps for the value? I am sorry for posting again. I thought I found a similar thread, but couldn't find it again after searching.

Thanks again
