The benefit of the XLR to RCA you link to at Amazon is making two audio pieces work together that don't have matching connections.
Even if your phono XLR out is true balanced the conversion to RCA at the other end means only two of the pins are being used. It now becomes single ended.
There is nothing wrong with the cable but unless you can hear the difference between the XLR versus RCA connector itself, there should be no benefit from this versus RCA - RCA.
