Amp for KEF CI5160RL-THX


I have these in wall speakers from KEF CI5160RL, they are rated to 200W i believe. I have an NAD C275BEE which i am trying to use for these speakers. i am just thinking about if i should get a more powerfull amp to power these speakers. 

I have currently the T777V3 AVR where the preamp is used to NAD C275BEE and the two KEF speakers are going to be connected to the C275BEE. While the rest of the system is going directly to the T777V3. 

Any suggestions if this is a good setup for now.
