In other words, can I rely on a path that would push an Atmos signal to the Marantz over HDMI, then out to the 88A for Dirac Live calibration, and then back into the Marantz through its analog 7.1 multichannel inputs to be powered and fed to my (passive) speakers?
Atmos Source >>> HDMI >>> Marantz xx10 >>> 7.1 Preouts >>> DDRC-88A >>> 7.1 INPUTS >>> Marantz xx10 >>> Speakers
Thanks in advance for you consideration and reply!
The loop back arrangement on the SR-xx10 series you're thinking of might not work.
The number channels the DDRC-88A is limited to 8, so while it will cover the floor level speakers (including the subs), you'll need a second unit if you want to have Dirac Live correction filters for the Atmos ceiling speakers (4 numbers). There is also the issue of time aligning two DDRC-88A units. A guide has been written up to do this if you're interested.
Also going with four ceiling speakers means getting an external amp.
As Mashie Saldana suggested, you can re-purpose the existing SR-7007 as an external amp for the DDRC-88A and use the internal amps of the SR-7010 to power the Atmos ceiling speakers. This will get the 7.1.4 Atmos setup. Note that in this arrangement, the ceiling speakers would be uncorrected. The levels and delays can still be setup up, but no Audyssey or Dirac Live filters will be applied.
