Make sure you have the turntable isolated properly, especially if you are on a suspended floor. My P8 is on a wall shelf, and it sits on a Townshend seismic platform. Sound improvement was huge with the Townshend, and foot falls non existent when I put it on a wall shelf.
There is a reason Rega sells shelves. Their tables sound better when they sit on them. Although I bought a Project shelf for a little over half the price :-)
