Can I ask all 009s owners!

I am very worried this morning. I spotted another post by realmassey about the dreaded 009 imbalance issue. He bought his pair only 3 months back from PJ.

I was told by Chester Audio in UK the issue was only the first batch in 2011, and was resolved.
I looked a bit further back, and many guys have had issues in the least 6 months with 009s less than 12 months old.

So, I am in a mess now. I love the 009 sound but can't justify £3500 on a phone that in 13 months 'may' become a paper weight. I am curious to know how widespread the issue is. I also think at this level Stax should give a lifetime warranty on the drivers, like many high end speaker manufacturers do (pending tests for abuse).

And would / does Stax replace a driver / drivers if the issue crops up outside of warranty. I mean, come on Stax the world most expensive headphone can become junk
in 13 months, this is ridiculous....

Can anyone shed some light on this?

 

I see you've posted on the other Stax imbalance thread already. I helped a friend pick up a Stax SR-009 in Jan last year and he noticed an imbalance issue. It was sent back to Stax and they replaced the drivers. I also helped another friend buy an SR-009 in June last year, tested it for about a week (or two?) and no problem cropped up so I sent it to him. As he's still waiting for his BHSE, he's not had a chance to test it I think.

 

I didn't have any problems with mine, nor did @Donnyhifi & @Wallabee. So out of 5x SR-009s bought in the range of Feb '12 -> Jun '13 that I'm aware of, 1 appeared to had imbalanced issue which appeared immediately (although deteriorated over the next few weeks) which was promptly fixed by Stax.

 

If you're buying the SR-009, hopefully you're having an amp to test it with rather than a lengthy wait for an amp before being able to test it. If so, get an interrim amp at least.

Hi Anakshan
Thanks for that.

So this issue IS STILL going on with new built 009s then obviously. I am sorry / worried about that.

So my questions are now:

1. Does Stax replace any defective driver out of warranty for free (minus shipping).
2. Does the defect show up in the first few months i.e has anyone had an issue much later on?
3. Has anyone found out what the defect is, and or how to cancel it out (static / discharge / run for a week ect).

This is a mess. Sorry guys, I am pretty mad about this issue.

I dont' know about "IS" but it "WAS" Jan '13. Whether all that's been weeded out in the past 16 months, I don't know.

 

1) I actually don't even know how old the warranty is. You should check with PJ if you're buying through them. On that note, to be honest if you're not willing to take any risks, then better buy from an authorised distributor rather than grey market import. Yes local distributor is more expensive but it it'll give you better peace of mind seeing that you're concerned about it even before buying it.

2) Good question. For my friend's, it was immediate. As he initially stated, when he tested it was probably a 5-10% difference between the L&R channel. After a few weeks that number increased much more but the channel never died completely.

3) Don't know what the defect is. In the repair receipt, it just said the driver was replaced. He hasn't seen any issues since the replacement.

 

Note that this isn't specific to SR-009 but it's happened to other models too. However, just to get a better understanding, are you an SR-009 owner? If so, how long?

post #2419 of 4899

Can it be noted for the last time..PJ offers the same standard 1 year warranty as 'authorized dealers.' As long as Stax keeps up with doing repairs from whoever, etc

it really shouldn't be an issue. It should also be noted that so far no one knows what's causing the issue or the fix. The biggest pain might be dealing with oversea shipping/wait time.

 

Also, this issue doesn't seem too widespread if you take into account how many units have shipped out comparative to how many imbalance issues have been reported.

I am to buy this week,having had the 007s for 2 years and various Lambda models (no issues)
for 25 years before then - Lamdda normal, Lambda pro, Lambda Nova Signature (brown frame).

I am told today by Synergy the UK importer the issue has not cropped up in 18 months, and it also
affected the 507 as well at that time.

They say no problems since. And in the UK you get 24 months warranty as a legal requirement in the UK.

There is NO driver lifetime guarantee, but they are saying if an issue occurred Synergy would sort
it out with Stax. This is a verbal promise. I would have no written confirmation or guarantee certificate though.

So, I have come full circle and will probably press on and buy the 009s. I am retired / fixed incomes so I can't
loose 3500 pounds like maybe some can? Dunno. Maybe I am paranoid?
But 3500 is a lot of money on phones, so you may sympathise with my plight?

However living without the 009 sound is also hell, as I have heard it now and need it!
post #2421 of 4899
Just to clarify: I bought my 009 from Cheshire Audio, an authorised stax uk dealer. The problem I posted about in the 'imbalance thread' was actually an amp issue, which has been fixed under warranty.
I has an issue with the 507 a couple of years ago and again the uk importer replaced them with a new pair.
Ah, I would never buy such an expensive item in Japan, i'm happy to pay a bit more and be covered by the official uk warranty...but thats just me
post #2422 of 4899

Ive had mine for 6 months and I have had no problems with them, even after a move to Korea which kind of had me worried for their safety

post #2423 of 4899
@astrostar59, IMHO, just go for it. As others have said and from my little personal experience, chances are low.

Test it when you get it. In the rare case if you have problems, you get great support anyway. And probably the most important thing is that when your problem is resolved the SR-009 is sonically rewarding that you'd forget you had problems with it.

Thanks, I think I will do that. The sound has ruined me forever!

Maybe the 009s having issues are mainly from PJ? Dunno. But it seems most issues appear
in a month or so, so I will be covered by Synergy UK distributor (UK Stax importers).

I'll post back here when I have lived with them a few weeks, and more importantly in 2 months
when I get back to Spain and hook up my Audio Note front end.

How do you divvy up your hearing time between the 007 mk1 and the 009 ? These recent posts have got my buyer's adrenalin pumping again !

post #2426 of 4899

Hi Folks,

 

I have an SRD7 - which is not working...

 

It appears to have 3 resistors that have been  cut in half (!) - 51k, 100k, 1M - and it is therefore delivering no bias.

 

It is an early 100V only unit - all the circuit diagrams I have found are for the later multi-voltage units

 

The other strange thing is that there is no 51k resistor on any of the SRD7 schematics, but it appears on one of the power input lines of the SRD5 schematic.

 

So it may be that I have an early production SRD7 with a circuit closely related to the SRD5 (I have not traced the circuit... was hoping not to have to !)

 

Does anyone know a tech in Melbourne (Australia) familiar with Stax headphones and energizers who could help with getting this beastie working again?

 

bye for now

 

David

Hmmm...that's kinda of a hard one 'cos I do have my mood swings and therefore so are my preferences. Having said that I think I do reach out to the 009s more than the 007Mk1s though. If I dare speak on behalf of my Tokyo Stax friends, for some reason we here in Tokyo seem to lean more towards the 009s whilst our overseas friends mostly seem to sway more towards to the 007Mk1s. To be honest, I don't really know why that's the case - maybe they get access to the BHSE more easily than us. Having said that, I've got an Electra.

Ok, let me ask this question this way: I am classic rock-only person. For this genre, what would you reach for ? I have the KGSShv and the Stax 717. Thanks

^. Just to add to my last query, my mood swings are between the Beatles and Led Zep, Pink Floyd to Deep Purple, Boston to Jimi Hendrix etc etc

My experience with the STAX Headphones is, if you have any imbalance problem, it will be from beginning on or will develop in a worse way very quickly.

My Lambda and the 007Mk2 are flawless from the start.

 

The 009, a early build version, had a slight imbalance problem from the moment i had it.

I thought it might disappear after some time of using, especially it was not noticeable after the headphone had some rest for about 10 days or so.

But i was wrong. It came back very quick and got worse and worse.

Since i own more than one Amp i was able to exclude a amplification error.

 

I decided to send it in for repair, but first they could not find any error. After the second attempt STAX Germany replaced it to a brand new Headphone.

Since then no problem at all and it works perfect.
