RCA terminations with a good shielded cable will work just fine for a short run like yours. XLR would be the better choice though.
If there are unshielded powercords in close proximity, they can cause hums, and hence hum rejection becomes even more important.
Check out some of the Canare LV-77S offerings by bluejeans and others. I recently bought a 50 ft run from one of the on-line companies and terminated them with RCA myself.
