Alright @benyl , figure I post my research on Atmos setups so I don't have to do it again in the future.
5.1.2, 5.1.4, 7.2.2 (7 and 9 channel) setups, not going to cover. There's so much cheap shit out there that'll do the job. Shit gets tricky at the 7.1.4 (11 channel) and 7.1.6 (13 channel) setups. Speakers, I personally go with cheap speakers, and good subs for best bang for the buck.
For a 7.1.4 11 channel setup, the cheapest route is to get a 9.2 receiver that can process 11 channels and output 2 channels to an external amp. Only 2 budget receivers that can do this.
Yamaha RX-A3080 (cheapest but hard to find these days)
Denon AVR-X3700H (has HDMi 2.1 support for better future proof)
These are 2020 models, so get 'em while you can. Royal Oak London Drugs seems to have it in stock.

There's a HDMI bug with the earlier builds but they're giving adapters to fix the issue. More info here.

You'll need to buy an external amp for the last 2 channels. Get whatever's cheap. So $2k for the receiver, and a few hundred bucks for a 2 channel amp.
If you want a cleaner setup, you can go with a 11.2 amp. Denon's AVR-X6700H does the job. Cleaner than a separate amp added to a 9.2 receiver, but definitely a little pricier at $4k.

If you want to go all out with a 7.2.6 setup, there's only 1 cheap solution. Denon AVR-X8500H 13 channel amp. Only thing else that processes 13 channels is discrete processors where you need 13 channels of amps. Fuck that.

Weird they're selling for $6k, last time I saw them they were $5k, Denon lists it as $5299 MSRP.
Good luck.
