tt ground to phono section. solid copper?

ok jea48 
thanks for the insight ..

     I have to have a ground on my vpi classic it buzzes like mad without it.I had it straight to my pre ground phone inboard.I am switching to the external phono,It has a ground terminal and a 2 prong dc conversion plug.My question is would it benefit me to go from it it to my pre ground also because the plug is not grounded ? The reason I asked may be a novice question,I remember when grounding large things to earth like a hottub a solid core wire is used it made me curious.Yes I use a 16 gauge stranded spaded wire now.
With acoustic zen matrix reference 2 cables which made a huge! difference over the blue jeans( another thread entirely) night and day ...

 vpi classic to musical fidelity mxvyl  phono section which has a grounding post next to rca  ( 2 prong dc conv plug for power ) then Rca to my intergrated amp . which also has a grounding post for its onbaord phono section which i was using until now .the mxvynl is new..Thats why i was curious if i should go from mxvynl to intergrated ground ?or it would cause a loop..i am not going to do that and will just roll with a tt to phono ground as per info.
Thanks

thumbs up
