Seeking recommendations for DAC to amplifier balanced XLR cable

After 4 more weeks with Sommer Epilogue XLR we compared it to Audioquest Colorado RCA which I had been using previously. Please not that we are not comparing apples to apples because Sommer is balanced. Finding number 1: the two cables are pretty much exchangeable, it is very hard to tell the difference. But Sommer is around $100, while the AQ Colorado was $450, 50% off list $900. A total waste of money. Finding number 2: if really hard pressed, I'd prefer the Sommer XLR to the Colorado. This can mean, however, that XLR is preferable between RME ADI-2 DAC and MF M6si. 

If the XLR cable is between differentially balanced components, there is very little difference between any balanced cable... they are all great

... which suggests that spending any more than about $100 per pair is a waste of money. Possibly Mogami Gold would similarly be indistinguishable from the Sommer I am using 

The best way to know for you and your ears is DO the test and IF the less expensive stuff is the sonic equal, sell the others and move on

In this case, the less expensive (but balanced) is not just equal but preferable (albeit very slightly). Will be selling the rest
