turntable with low hum

just set up the Sonos 5 speaker. Our existing turntable and Optimus amp work just fine on our old speaker. We wanted to upgrade to the Sonos 5… but when hooked up, there is a terrible low hum that gets louder with volume increase and is persistent when the record is finished or in-between songs when there is no sound. 

the grounding wire is fine and like I say, does NOT have the buzz with the older speakers. 

So what are we doing wrong? Or is our system no compatible with the Sonos 5? 

We do NOT get the buzz with any of the other features, meaning the streaming music, etc. Only when using the record player. 

If we can’t fix I guess we just go back to the old speakers because that hum is giving us a headache.

Yes ceramic. If switched to the other it is terrible sounding. 
we did the source level per your instructions and it really just changes the hum but doesn’t eliminate. Unless there is anything else to do we will be returning. We love the other features of the Sonos 5 but want to continue using our current record player. Really appreciate your help trouble shooting this!

You could try connecting the ceramic cartridge directly to the Five, removing the ancient amp entirely.  The level may be adequate, though you might need some manual EQ. 

The rest of your kit is decidedly ‘vintage’ so I can understand why you might want to stick with what you know.
