The useful differences

What changes when you use it

The soundbar compresses the system. The receiver exposes every component so it can be chosen and replaced separately.

Receiver-only and soundbar-only prices are not equivalent.

Choose the maintenance burden

Decide whether you want one supported ecosystem or separate parts you can replace and configure independently.

Ownership style matters after the first movie.
