RCA versus XLR interconnects

ghdprentice, Pedantic, perhaps, but some manufacturers put xlr inputs and outputs on components which are not truly balanced. Merely attaching xlr cables to them does not make a balanced circuit. For edification you might google Balanced (XLR) and Unbalanced (cinch)connections by Christiaan Punter owner of HIFI Advise. At the risk of adding redundancy to pedantic, the difference between a 1 meter cable will, except in rare circumstances,  be differences in the effect of the connectors and wires used. Both of which would IMHO dwarf any differences caused by the noise isolation benefits of an balanced XLR cable. Your turn. :-)

Have you searched the forums?

If you have balanced equipment then XLR is the way to go. I have SPL, Gold Note PA-10 and they are balanced. 

Doesn't matter as the electrons don't know nor care what they travel upon. 

Well, it might matter. It depends, yeah.
