I'm not sure about the 505uxii but XLR cables on my 590AXII made a rather significant difference in comparison to single-ended in my system. Balanced connection between the amp and DAC.
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.
