Context: I've been running my 5.1 system for 12 years and have been very happy with it, but we have moved to a new home and I have to change my speaker configuration. My primary use is streaming or UHD movies. Room is My old Rotel has to be replaced so I can play the new formats and start playing with Atmos. I've decided to go for a 5.1.2 driven by a Denon 2400H and Sony X800. I want to keep my mains which are B&W Floor Standers DM603 S3 and my Martin Logan Sub. My Surrounds and Center have to go in-wall now as do the Atmos Questions: I'm looking for some affordable rectangular in walls for surrounds and center that will balance with my B&W mains. Considering Klipsch 2650-W or 3650-W II for surrounds and 2502 W or 5502 W center. What do you think? I want to use round in-ceiling for Atmos. Maybe KEF CI50? Really have no clue how far I have to go for Atmos.
