Proper Ground for Tonearm and Turntable

Hello all,
My first experience with a high end turntable an Acoustic Signature Triple X has a ground on the plinth as well does the Tonearm have a ground cable attached to the RCA cables. I am getting a pop thru my amp when the needle hits the record even if the amp is muted. Should both the plinth and the Tonearm be grounded to the phonostage? What is the correct way to ground this to eliminate the pop?
