The Playbar, Sub and Ones are not Bluetooth speakers and they aren’t equipped with RCA or line in ports. You will need to add a Sonos Port, Amp, or Five to connect your turntable and play music through your Sonos home theater setup.

Do you know the Pros and Cons or the Port, Amp or Five? Or which would be the best?

Here is a good article explaining your options. It even includes the discontinued Sonos products you could purchase used on eBay if you wanted to save some money.

I would say your best option would either be the Port or the Five. The Port is the least expensive option, but the Five gives you an extra speaker. And the Five sounds fantastic.
