Convert Martin Logan 11A Impressions from RCA to XLR (Unbalanced to Balanced)


I currently own a pair of Martin Logan 11A Impressions. My question is can I convert my RCA jacks on the back of the speaker to XLR (balanced) jacks. I've read a direct injection box can make this happen.  I've been told that the change will yield better sound with less noise.

Thank you.
