Trying to decide on an AVR or seperate DSP and amp...please help

I went with the Klipsch THX inwall series speakers because I was able to get a really good price on them and they seem pretty nice anyway. Now I need to decide on what I'm going to power them with. Is there an AVR that would run these nicely or sould I just go with a seperate 7 channel amp and DSP?

Here are the speakers I got;

LCR - KL-7800-THX

SIDE SURROUND - KS-7502-THX

REAR SURROUND - KL-7502-THX

SUB - TWO KW-120-THX

SUB AMP -KA-1000-THX

Would an integra dhc-80.3 and a dat 70.1 run these speakers nicely or should I look at something like the wyred 4 sound mini mc 7?

Still trying to figure out what I need to get to run these speakers properly. What should I get?
