You can probably find someone to do it for less as a custom order. Whether it is done properly or not is another matter.
There is a difference in what it takes to make a cable that works correctly when the transducer you're driving has anywhere from 100x to 1000x the resistance of the cable (which is a trivial job) than when the transducer itself is 1/10th the impedance of the raw wire involved! Left/right resistance has to be VERY close. Even a few early official RAAL cables had issues with this.
I made my own ... though that wasn't about cost savings - the end result used raw materials that cost more than the finished RAAL cables.
One of the hiccups with getting a custom-made cable for the Raal is that the XLR end is a female 4 pin XLR. It's the only headphone that uses this configuration. Moon Audio makes a custom Raal cable, but it's comparable in price to the replacement from Raal.
I also made my own cable for considerably less than $500 in materials. The Raal cable is nowhere near $500 in materials, either. I don't fault them for making money on accessories, and want very much for them to be a be a successful company making profit on these phenomenal headphones, but I could make the stock cable for $75 retail and two hours of my time, and that's being generous.
There are four identical strands of relatively thin wire in there, even if they're OCC silver they appear to be little more than hookup wire. The TRRS connectors are unbranded, and while they appear to be of reasonable quality they're nothing too special. In fact, there's no need for TRRS connectors whatsoever. There are only two wires entering the TRRS connector, and the tip is tied to ring one, with ring 2 tied to sleeve. It could be a TS connector, an HD800 connector, a whatever connector. I think TRRS was chosen purely for (relative) rarity and the perception of high end, as it's totally unnecessary.
Good info. thanks. What type of conductor did you guys use in your cables?
