other options i would look at if it was me would be an even older but good 5.1 AVR from craigslist with 6ch input so you can run all 4x your atmos speakers off the one amp OR look for a used NAD power amp or something similar to drive your front channels. either option will be really inexpensive if you look for the right deals.
I think when it comes surround and height it doesn't really matter, the best option will to get Emotiva for the LCR and use AVR for everything else.
to me i would think having all 4x atmos channels at the same output levels across the volume range is rather important, if you power 2x atmos from your amp and 2 from 2nd amp, keeping volume level at second amp at say -20db will result in different mis matched levels depending on your main amps volume. easy way to see the issue is to hook it up like that and playback an atmos channel test video at a mid volume and then again at a high volume, your atmos speaker levels wont be equal which basically removes any point at all in your new avrs awesome speaker calibration/room correction stuff. powering your fronts with the second avr will still sort of suffer from the same issue, but its not going to be as apparent, since your front sound stage is nice with adjustable volume
You want your 7.1 to have the same sound level because those are your main sound CH, then you can use a sound meter with the Dolby Atmos Sep Disc to match the FH and RH.
What do you think
