not sure what I am doing wrong here

this is my setup

Technics SL120M7L turntable with Ortofon Concorde MKII cartridge

connected to a Project Phono Box (grounded)

then connected to the Sonos AMP

Dali Oberon 3 Bookshelf are connected to the amp

good news is when I steam Spotify to the amp the sound is incredible from the speakers

When I do line in for the turntable its low volume and distorted if I turn it up high its awful, there is an issue with the input from the SL1200 to the AMP but I cannot work out what it is…

any ideas or advise would be extremely appreciated

I “think” its the phono box but not sure does any have SL1200 setup and working with an AMP if so what are you using ?

The shorting plugs are just a test. When you attempt to “play” the plugs there should be silence.

I slept on it woke up, dismantled everything from current location moved it to a room where there is nothing going on, reconnected all and it works! something was giving an interference for the humming noise what I am not sure…. it was in close proximity to an ARC with AMP connected to my Sony TV….

There may have been a strong magnetic field near the wires, preamp, or turntable. And, there are silly things, such as plugs not fully seated in their jack. Unfortunately, you accidentally “cured" the issue with the move and didn't learn the maximum.
