Is this basically 4 scaled up / higher power STA-100 in a single chassis?

Yes, plus the multi-zone buses.

Hi I have Dynaudio Contour 20 as surrounds in my HT.
Will the MCX-800MZ be able to drive them, as well as 4 smaller in ceiling atmos speakers, and mute the 2 last channels?
Dynaudio are well known to be current hungry.
As I understand it the MCX-800MZ is a 4 x 2 channel configuration in one box. But it does not mention the power supply, only Watt.
 
I have chosen 3 x AMG ONE for LCR with Contour 30 and Contour 25C, the AMG ONEs are wery good with these speakers
But do I need another set of AMG ONE for the surrounds, or will MCX-800MZ do the job?

I also have an MCX-4 but will sell it, if MCX-800MZ is up to the job in my setup.

No problem.  There is no mention of power supply because the module for MCX-800MZ has the amp and power supply integrated on a single board.  Each stereo channel module has its own power supply.
