Dedicated phono cables, besides having a separate chassis ground, are usually much lower capacitance than line level cables. The XLO site shows a distinctly different cable for their phono. My guess is that there is less wire (higher gauge) to keep the capacitance down.
None the less, it does not hurt to try it. You may have to change the capacitance setting though.
