Power Amp & Integrate Amp

Hi,

I currently have a Marantz Pre-amp that supports 11.2 configuration and a Monolith 5 channel amplifier. My current setup is 5.1.

I am looking to add 2 Atmos speakers for a 5.1.2 setup. Can I add an Integrated Amp to this setup to power the 2 additional speakers? Will it be effective? Or I should be looking at Power Amps only.

Any recommendation for Integrated Amp or Power Amp for my current setup will also be appreciated.

Thanks
