Connecting a non-Naim CD Source to a NAC102

I'm hoping to buy a NAC102/NAP180 in the near future; however, while I save money to buy a CDX I'd like to use this with a non-Naim CD source.

I assume that the 102 does not have RCA inputs so the question is how do I connect the CD player? I guess an RCA - DIN cable is the answer and, if so, does anyone know where I can buy such an item?

Also, is there anything to be careful or aware of when doing such a thing?

Thanks,
Jack.
