Female XLR to RCA?

@blisshifi an SPL Elector to a Musical Fidelity X-P200.

@ghdprentice thanks So I can cross that off my list.. 

@ michaellent the preamp I’m looking at has three balanced inputs and three RCA unbalanced inputs. I would be using the units’ unbalanced RCA inputs as I have no balanced out puts on any of my sources. Neither would I be wiring these cables myself. It would be a short run. 4 feet max, most likely 3 feet. I would be purchasing them from an audio cable manufacturer. Here’s the link.

I’m just looking to connect my amp and preamp in such a way that it doesn’t explode when I power it up.
@elliottbnewcombjr thanks. I think you just gave me the answer I was looking for. My system doesn’t have any hums or buzzes in it. In fact it sounds pretty goddamned good if I do say so myself. Right now my system is all RCA to RCA. I’m looking to upgrade from my Musical Fidelity M2si to possibly an SPL Elector preamp (one of many choices. It’s the only Solid State preamp I’m considering.) and the ONLY variable out put on it is an XLR (female) out. (Why do manufacturers do this?)
@richopp I’m looking to possibly add an SPL Elector Preamp to my system to replace my Musical Fidelity M2si. Iv’e been using the M2si as a preamp to feed a Musical Fidelity X-P200 which is RCA inputs only

SPL makes pro products as well. That's probably why the Elector has XLR outputs. If you're running a PA system or a Recording Studio this makes sense.

Thanks for the sound advice. A friend of mine referred these people to me for replacing old interconnects. They're out of Seattle Washington. I bought three sets of RCA terminated interconnects from them. I have no regrets buying them.
