It may also be an isolation issue.
Ideally your turntable should be located away from the speakers (and not in their line of fire) to minimise floor-borne and airborne vibration feeding back through the turntable 'system'.
Turntables without sprung sub-chassis can be more prone to feedback ,especially if your speakers and your turntable are both sited on a suspended wooden floor.
If practical, try a wall mounted support for the turntable like
this one from Project.
Rega also make a wall support that is a little more minimalist but only fits Rega turntables.
Optimally a wall support for a turntable should be mounted on a load bearing, masonry or brick wall.
