recabling, seriously, should take well under an hour if you're experienced with an iron and soldering itself.
The first post in the thread explains most everything you need to know: just don't try using a Philips size 0 screwdriver, as it's too big.
I was trying to find a supadrive 0, but they're really difficult to find, so I'll just go for a 00 or 000 instead.
For information, each of the Mogami cores is around 1mm in diameter, so some 3.5mm heatshrink should be fine.
I used some duct tape on the inside of mine - round the cable, it then tucks nicely into the curve.
Mine also had some glue holding the cable in. I'm also 100% sure I put the cables in the right places, but I've tested with Focal disc 2 and know that the phase in one ear is wrong. I'll correct that when I stuff them, after I get some heatsink. I don't want to take them apart too many times.
