\rHi Marcel:Yes, the Preamp1 will work with your Marantz but note that the internal Phono preamp is limited to MM, a Moving Magnet Cartridge. The problem will be locating a new preamplifier that would have a differential output so you could run Balanced Line connectin to get the full potential of the Marantz. I found a $400.00 Rotel with XLR outputs on eBay. Typically, it would cost more than MDF price of your amp to find another Balanced Line solution (even a used one at that).TL/5615\r
