Tachikoma Posted March 24, 2017 Report Share Posted March 24, 2017 Wait, how did you crack the drivers open in the first place? Aren't they glued shut? Quote Link to comment Share on other sites More sharing options...
DefQon Posted March 25, 2017 Report Share Posted March 25, 2017 (edited) They sure are, more like varnished shut and its a cunt separating the stators from the inner diaphragm ring without putting too much force potentially bending them. I learnt this the hard way with a LNS though it was already broken. Then I found it easier to clean off the varnish around the drivers first leaving a thin coat giving you easier access to the stator and diaphragm ring. Use a very thin, sharp and strong scalpel or surgeon's knife. Edited March 25, 2017 by DefQon Quote Link to comment Share on other sites More sharing options...

Arthrimus Posted March 25, 2017 Report Share Posted March 25, 2017 Well... The channel imbalance is gone. Thanks for the help Pirx and DefQon. Your posts gave me just enough information to get confident. The driver split apart just as expected and the recoat went without incident. They're singing properly for the first time since I've had them! 8 Quote Link to comment Share on other sites More sharing options...

It's the same stuff I used to recoat my SR-5s a couple of years ago and it's held up fine. Edited March 25, 2017 by Arthrimus Quote Link to comment Share on other sites More sharing options...
Torpedo Posted March 25, 2017 Report Share Posted March 25, 2017 Thanks! It's kind of paradoxical using an anti-static cleaner to coat electrostatic drivers. 1 Quote Link to comment Share on other sites More sharing options...

It really isn't. The anti static stuff is just that as it creates a high resistance layer which is perfect for electrostatic use. Quote Link to comment Share on other sites More sharing options...

The anti static stuff is just that as it creates a high resistance layer which is perfect for electrostatic use. Sure, I get it, that's why I said "kind of" paradoxical. As I understand it, considering my very low knowledge, you want your electrostatic field to be perfectly controlled in intensity, to be the same on both drivers, and to be kept within the strict size of the material. An isolating layer can be very helpful to achieve that. Is the problem in the 009 losing its balance between channels related to this?

Ali-Pacha Posted March 26, 2017 Report Share Posted March 26, 2017 Some say it could comme from a rivet connection (instead of soldering) within the strain relief for the bias. But who knows... Ali Quote Link to comment Share on other sites More sharing options...
kunalraiker Posted March 26, 2017 Report Share Posted March 26, 2017 So eventually all SR007's and SR009 will develop this channel imbalance? Would that be the case. Quote Link to comment Share on other sites More sharing options...

Unlikely. The 009's were affected with some imbalance issue due to theories that Birgir has posted here and on the other site a dozen times. Probably Stax using a different coating or pre-mature batch of drivers. The O2's on the other hand have been solid since release, rarely you would see anyone posting issues with those having channel imbalance. At the end of the day how the headphones are handled and stored in the type of environment condition affects whether or not the drivers will turn to cack. Humidity and direct sunlight placement of the headphones can affect the headphones overall. 1 Quote Link to comment Share on other sites More sharing options...
Dave R Posted March 27, 2017 Report Share Posted March 27, 2017 I got my 009's in late 2011 and haven't had one problem of this imbalance, although I did have a problem with the cable last year in which I had to have a new one fitted, but I also had to have a new cable fitted to the 007mk1's I once had, this was after I'd had those 007's for 7 years. I got those 007mk1's in 2000 along with the SRM-007t to drive them, but let them both go in 2011 because I was never that impressed with the SQ the two produced, I've since heard 007mk1's driven by the BHSE and regret letting those mk1's I had go.?

That seems to be the combo hitting the right sound signature that everyone enjoys generally. The O2 MK1 with Blue Hawaii SE. Quote Link to comment Share on other sites More sharing options...

When I ordered the BHSE early 2011, it was actually for those 007mk1's, however after hearing the Esoteric K-01 around August 2011 I stupidly used those earspeakers as part exchange for that SACD/DAC. Now I like to think I've only made 3 mistakes with audio gear, 1, was getting the SRM-007t, 2, letting the 007mk1's go, but by far my biggest mistake was getting that K-01, fucking idiot I am. 1 Quote Link to comment Share on other sites More sharing options...
Sorrodje Posted March 27, 2017 Report Share Posted March 27, 2017 Hello, I have a good ol' SR202 at home and I want to change the pads. I already pulled off the old pads and removed the old double sided tape but there's still a lot of thick sticky glue I struggle to remove. I tried acetone and no success thus far. I would like to do it properly and clean the cup before to apply the new double sided tape and the new pads. What method/product do you suggest usually?

n3rdling Posted March 27, 2017 Report Share Posted March 27, 2017 I usually get most of it off by scraping a scalpel or credit card across the plastic. Quote Link to comment Share on other sites More sharing options...
Sorrodje Posted March 27, 2017 Report Share Posted March 27, 2017 @n3rdling : most of it yup. Already thought to that but for example the screws I can see are covered with glue. I can take the time to scrape that properly but I wonder if a product could help to make it perfectly clean. Quote Link to comment Share on other sites More sharing options...

I have not used this in your particular case, but Goof Off Professional Strength Remover has never let me down on other nasty adhesive removal jobs. In the US, Home Depot carries it. Don't know if it is available in France/EU http://m.homedepot.com/p/Goof-Off-16-oz-Professional-Strength-Remover-FG654/100671841 Edited March 27, 2017 by Laowei 1 Quote Link to comment Share on other sites More sharing options...
