ok thanks for that.... I spoke to the retailer where we originally bought the Marantz from and they said I do need a phono preamp as the Marantz doesn't have a dedicated phono preamp
But because I didn't buy the preamp from them, they suggested I contact the place I bought the preamp from and ask them.... so I'm kind of going round in circles
I might see if I can contact the manufacturer of the record player....
