Home Theater Processor

soix, thanks for the reply, my system is more for HT but I do like to listen to music as well, about a 70/30 split.
Currently running B&W 802 Matrix in the front and B&W all around.

The Classe sigma SSP mk2 does atmos, but you could also look at the Marantz 8802. 

The Mcintosh MX122 is also an option. It’s the baby brother of the Mx160. 

Keep an eye on the HDMI version of the units you buy.  Without at least 2.0a, you can’t get HDR, which is probably more important than 4k at this point. 

Marantz 8802A or the NAD M17 V2. 
If you're looking at the 10k'ish range I would go with something modular for future upgradeability like the Theta Casablanca. 

Sorry, I could care less about Atmos. :)

Best,

E
