Yes, Meridian supports Atmos through their 271 Digital Theater Controller. Its good you started this thread, sometimes you can get an expensive system that rivals systems costing multiples more. When you spend a lot, you risk a lot. Having a Meridian system that is engineered from the ground up not only removes a lot of that risk, it can go beyond what an equivalent chain can achieve for the same price. Look at the specs on the DSP 8000XE. They weigh almost 250 lbs each and have 1250 watts of internal amplification. As good as the specs are they sounded even better than I imagined, dynamics were shocking and you don’t need a sub for sure:
