Technically speaking there should be a lower floor noise using XLR vs. SE, however if you are using a 1/m pair of interconnects I'm not sure you will be able to hear a difference in sonics. If you leave the volume at the same level the XLR will definitely sound louder then the SE, but in my opinion you wont hear improvement unless you have a need to run long interconnects.
I use the ARC Reference CD 7, ARC Reference 3 Preamp and Plinius Reference amp. I had to switch out some XLR interconnects to SE interconnects because even with the volume control set at the lowest level the volume was still louder then I wanted it, for example if I was listening to music and had a phone call or was talking to someone next to me.
