I'm tempted to get these. I've located a reasonably priced set of balanced cables. http://www.ebay.com.au/itm/HIEND-Upgrade-Cable-For-SENNHEISER-HE-6-300-400-500-560-Balance-XLR-4pin-CANNON-/121413451205? He had the header wrong with :Sennheiser" instead of "HIFIMAN" but he will correct that. He says he will supply two neurtik female plugs for the same price if you prefer that.
