I'm having trouble with intermittent signal loss due to problem at strain relief/cable entry. If I hold the cable near the strain relief and twist it, I can get the signal back, so naturally I'm guessing that something is loose. The problem is that I have no idea how to take the strain relief apart, let alone any experience with a soldering iron to fix it. Does anyone have a suggestion on where to get this fixed? I've noticed that Yama's is not the best place to go, and besides this pair is beyond its Japanese-only warranty period. I'm cool with a whole recable or something like that, but I don't see any examples of work done on any of the small-time headphone cabling shops I've found online. APS has done some retermination work for stats, but that's about it.
