Isn't that RCA outputs put out 2.2 volts and balanced put out 4 volts ? I have a cd player with both RCA and XLR outputs. The other day out of curiosity I used an XLR to RCA cable to connect it to my amplifier. At the beginning I was positively impressed by the better sound I got, with a bass twice as big and a more solid image. However, after a while I realized that the piano was edgy and I had the general impression that the sound was too 'pushed' toward me. So I second what Jmcgrogan2 said, make sure that you like the sound before buying the cable.
