If you want to go with Atmos, then the QS8s will have to be replaced with bipolar speakers like M3 or M5.

Since I upgraded to Axiom version 4 speakers which included a VP160 centre and QS10 surrounds, I don't feel I need Atmos. I'm not saying Atmos isn't cool; I just feel the 5.1 I have is good enough for me.

Adding high power amplification like the ADAs has moved my system to an entirely different level. I run a 7 year-old Onkyo by the way.
