anetode Posted September 30, 2011 Report Posted September 30, 2011 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.
CherryBomb Posted September 30, 2011 Report Posted September 30, 2011 Find a DIY friend. Probably do not ask someone you do not know. Another idea is to contact APS. Good luck.
DouglasQuaid Posted September 30, 2011 Report Posted September 30, 2011 I've pulled my sr007 apart. If i'm on the same page with you here, you'll have to disassemble your driver housing to get inside the piece you're looking at. Not a very minor job. Yamas wanted $1800 for driver replacement (replaced with mk2)... more expensive than just getting another sr007 mk1. They're awful and should be bypassed whenever possible.
anetode Posted October 1, 2011 Author Report Posted October 1, 2011 Find a DIY friend. Probably do not ask someone you do not know. Another idea is to contact APS. Good luck. I don't have a DIY buddy, this thread was me asking people I do not know Yamas wanted $1800 for driver replacement (replaced with mk2)... more expensive than just getting another sr007 mk1. The drivers themselves are fine, it's the cable connection that's cutting out. From some of the posts I've researched this can be blamed on poor strain relief.
manaox2 Posted October 1, 2011 Report Posted October 1, 2011 This is a major weak point of the O2 mk1. The mk2 made changes to help this. Really sorry to hear it has struck again.

justin Posted October 1, 2011 Report Posted October 1, 2011 i had to replace the cable on my pair. it wasnt a bad connection at the driver as i suspected, but the wire(s) had eventually broken below the strain relief, requiring the entire cable to be replaced. i think i bought the cable from Kuboten.
spritzer Posted October 1, 2011 Report Posted October 1, 2011 Stax have been laying down the law as of late so sourcing parts is getting more and more difficult. If you can get a replacement cable then the swap is easy enough but the common rules about working up close and personal with electrostatic drivers have to followed to the letter.
screaming oranges Posted October 1, 2011 Report Posted October 1, 2011 Are there any handling precautions or, better still, actual physical precautionary mods that can be done to a pair that is in good working order to lessen the risk?
deepak Posted October 1, 2011 Report Posted October 1, 2011 Are there any handling precautions or, better still, actual physical precautionary mods that can be done to a pair that is in good working order to lessen the risk? What I do is use the SRE-725 extension so there is plenty of slack on the cable and you never have to worry about running out/snags/etc
luvdunhill Posted October 1, 2011 Report Posted October 1, 2011 Learn how to pack them in the box helps too. I'd recommend to the OP to sell them (disclosing the issue obviously) and buying another pair.
cobra_kai Posted October 1, 2011 Report Posted October 1, 2011 Is the the cable going into the cups were the issue usually occurs or on the plug end?
spritzer Posted October 1, 2011 Report Posted October 1, 2011 It's right next to the (ineffective)strain relief on the cups.
swt61 Posted October 2, 2011 Report Posted October 2, 2011 I actually wish we had a better solution for anetode, as that's the same reason I found the other site. Which of coarse lead to this one.
anetode Posted October 2, 2011 Author Report Posted October 2, 2011 Thanks all for the suggestions. It looks like there's no easy solution, so I'm going to keep my eyes peeled on replacement cables hitting up the marketplaces, and try to solicit a few pro modders/recablers to see if they're willing to take on the project. Otherwise, it's really about time I got some tools and learned how to work on replacing parts.
cetoole Posted October 2, 2011 Report Posted October 2, 2011 I wish there was a way to source replacement cables, I am just slightly paranoid that mine will get broken at some point too. Looks like I am about at the time for an elastic replacement too, the headband is getting pretty saggy.
Tachikoma Posted October 2, 2011 Report Posted October 2, 2011 I got a new set of O2 cables via EIFL, can't see why they won't continue selling those unless Stax pulled the plug on them.
justin Posted October 2, 2011 Report Posted October 2, 2011 I got a new set of O2 cables via EIFL, can't see why they won't continue selling those unless Stax pulled the plug on them. to force you to pay crazy repair prices from their distributor, who probably isnt even going to respond to you
spritzer Posted October 2, 2011 Report Posted October 2, 2011 The UK service guys have been pretty responsive and helpful in the past so it is well worth it to contact them. I would stay away from pretty much all of the cable guys since they have zero soldering skill. Soldering these cables is no joke as you are soldering directly to a high precision driver and excessive heat, flux castoff etc. will destroy the drivers. There is a reason why I use a soldering station with very high temperature stability...
DouglasQuaid Posted October 3, 2011 Report Posted October 3, 2011 The drivers themselves are fine, it's the cable connection that's cutting out. From some of the posts I've researched this can be blamed on poor strain relief. I only posted that to give you an idea of how blatantly they hammer people for repairs.
