Help VPI turntable hummmmmmm


I have just installed a new Naim system with a VPI Scoutmaster and the TT hum is not quite deafening..............but getting there. Can someone please help!! Do I need to earth the TT to the phono stage? If I do I have tried this but no success. What am I doing wrong. There is also an audible 'thump' when switching the TT motor on or off.

Call vpi. They are very helpful.I am not saying you do not have a tt ground problem. Most sounds are caused by the cart. Is it properly attached? Loose wire? Wires not connected properly?
Grounding the unit to other than the phono stage may help? Ground it to your pre or even to a screw on the plate cover on the wall plug?

Are you using a high gain cartridge with a low gain input? Is this hum as soon you you switch to phono on the pre or only when a record is playing? We need more details to help narrow down the problem.
