XLR cable splitter?

I will have both a A/V pre-amp (McIntosh MX 135) and headphone amp (Donald North Audio Stratus) that has XLR balanced inputs whose signals will come from a Yiggy DAC which has only one balanced output but 2 unbalanced outputs.  

I prefer balanced but would require a XLR spitter so both the Mac and HP amp get balanced signals.  First, am I better off with just using the unbalanced RCA output on the Yiggy for one of them as there would be signal degradation using a splitter?  If not, which spitter would you recommend?
