Should I try XLR?

I've never tried XLR cables, just regular ICs with my components. I currently have a Luxman 505UXii integrated with Dynaudio Special 40s. My CDP/streamer is a Marantz ND8006. I'm currently using WyWires ICs with all of my equipment. Would adding XLR cables to the CDP/streamer make a huge difference---if so, should I stick with WyWires XLR or something else? Thanks in advance for your help.
