Also from that post I have this that does level match;
I do not see where the Oppo's specs indicate a problem if you use a pair of RCA to XLR adapters. For example, the Parasound Zphono XRM's balanced output impedance is 150 Ohms, which is fine for the Oppo's 15k Ohm input. The Parasound has sufficient output to drive the Oppo (I would not be surprised if the output is higher than rated). Finally, the Oppo's maximum input, at 18V, won't be clipped by the Parasound or any other phono preamp. The Oppo's XLR line input should be compatible with any typical phono preamp.
I like keeping things as simple as possible for best sound quality. Thus, I would try using RCA to XLR adapter plugs or cables first, then consider alternatives later if a problem occurs.
