I believe you are mixing up terms.  To use a turntable with Sonos, you need two things; a Sonos device with a line-in (Amp, Port, Five, or an Era speaker with line-in adapter) and a turntable with either an internal or external phono pre-amp.  The phono pre-amp converts the RIAA phono mastering to standard line-in for use with the Sonos line-in, and is not to be confused with the Sonos Amp.  All turntables sold by Sonos have an internal pre-amp.

Thank you jgatie --- I was hoping to keep it simple and affordable for sure.   Is buying the package maybe the way to go --- I think there is one where you buy the Era speaker with the turntable, thatway I could then distribute the turntable sound throughout out the house?

That would work. 

I have a 17 year old Pro-Ject turntable hooked up to a pair of Fives and a Sub Gen 3 (using an external phono pre amp as my turntable does not have one). I can highly recommend Pro-Ject as a make.
