Upgrading HT and 2channel stereo


Hello,
  New to Audiogon’s forum, but seems like a proper place to discuss audio topics, so here goes...

   Will be replacing my 2008 Onkyo TX-NR906 (AVR) and looking for suggestions on components.  Leaning towards separates such as a multichannel amp and AV processor for HT application and an integrated amp to run the front L & R speakers for stereo.  Welcome other configurations, but would like to keep costs for these three separates below 10k.

   Equipment I will be using with new components:

   Speakers-front left, right, and center are Sonus Faber Domus Concerto     
    Rear speakers are Totem Limks
    Sub is a REL R-505

  Existing components that will be retained and used include Oppo BDP-103D; basic Roku box, cable box and a LG OLED C9 TV.  

  Components I’m considering, but not set on include the following:
    AVR:  Anthem MRX1120
     AV pre pro:  Anthem AVR 60, Marantz 8805
    Multi channel amp:  Parasound A51/52/52+; NAD M27; Classé Sigma 5

  integrated amps:  Hegel; Rega Elicit R; Anthem STR

  welcome thoughts on this upgrade project including other brands including ATI, Emotiva, etc.  thanks in advance, Mike

Why get the 1120 if you're not going to use the amps? Get the 720 which has the same number of channels minus a few amps and the bigger toroidal power supply for $1000 less. The room correction software works great. I just upgraded from a MRX 300 to the 720 when the sub out on the 300 broke. 
If I were to go with the MRX and integrated amp configuration, would components have HT pass thru/bypass?  Given my speaker’s stats, of the two integrated amps would one be preferred over the other?  
Agree that the 1120 might be overkill, so a 720 is probably a better match, plus it would allow greater flexibility should I add additional speakers in the future.  Not hearing any discussion on Emotiva, ATI, and similar manufacturers, I will remove them from the list of consideration.  Thanks all.  
When I first got my MRX300, I used a 250WPC Parasound 5 channel amp I already owned, was using Vandersteen 2Cs and their CC and surround speakers. When the amp broke, I just powered everything off the Anthem and honestly didn't notice much difference. I use the 720 to power my Salk Supercharged LCRs and the surround and atmos speakers. 
Much better now that you can use ARC with a Mac and not have to connect a PC with a serial cable like with the 300.
