Do I need a receiver for a soundbar setup?

No. Soundbars are self-powered and connect directly to your TV. A receiver is for discrete speaker setups (bookshelf/tower speakers + subwoofer). Receivers deliver far better sound but require more speakers and setup.

Can I add Atmos speakers later?

Yes — 7.2 receivers let you start with 5.1 and add two Atmos height speakers later. The receiver handles the reconfiguration in software.
