Those are very nice resistors! And nice solder too, I haven't heard of them until you mentioned.
I've thought about buying some pre-braided cables from eBay and then removing the terminations, but the problem is the lack of 4-strand options for balanced. And I also want to use my own y-splitter and perhaps add a ground channel.
Why ground? Well the stock 4-pin Hifiman He1000 balanced cables have 3 wires per channel, the only thing I can think of is the headphone needs a ground channel for some reason.
