@rlsammie I only have one system for both music and video ;-(. Probably the only Dolby Atmos capable system in the world with no center channel!
There are some seriously good Atmos sound recordings available too. If you like classical then Norwegian label 2L at www.2l.no has some stunning disks. In my opinion, they are world leaders in how to do digital properly. Elsewhere, Pink Floyd’s Dark Side of the Moon in Atmos is amazing.
For others embarking on the high-resolution disk journey, HDMI can be used to mix and match transports and DACs from different manufacturers, and supports high resolution audio including multi-channel DSD and Atmos. Mcintosh is an exception, and the MCT500 SACD transport is 2-channel only!
