They're pretty easy to make too. I actually was planning on making another order with Markertek for some parts if you're willing to cover shipping to you, parts and split shipping from Markertek to me I'd be glad to make you any adapters or cables you need.
I need a y cable 1 to 2 feet long with 2 female 3 pin XLR to 1 female 4 pin female xlr to hook up a DAC1 to standard balanced cables (does this make sense to you?) I also need a balanced cable for a set of Hifiman cans. Let me know what cost range Im in.
