Multi Room Speaker System For A House

Hello to all of you.

I apologize if this has been discussed previously, I have skimmed over this subscriber list. My dad needs some assistance with wireless speakers.

He would want a wireless multi-room speaker system that is connected to Bluetooth or Wi-Fi. I would also like to be able to play various music in different places at the same time country in the kitchen, for example, and rock in the living room. An app that managed everything would be really beneficial.

Is Sonos the best option available? They consistently surface in all of my investigations.
