In my experience, an RCA->XLR cable sounds better than the RCA->RCA link.
If you're adventurous, one experiment worth trying with the RCA->XLR cable is to find a cable where the XLR cable's ground pin is not connected to the RCA side. I find it gives a much smoother, detailed and 3-dimensional sound. But you could run into dropouts for high bitrate signals depending your cable length and environment.
