The Stax Thread III

[KDS315]

I guess a T2 will be better than all those mods.

as a T2 is rather Unobtainium, this is a rather limited proposal

seek and ye shall find - they are available for commissioned build.
the wait is long.......but worth it

A T2 would be great to audition but living in New Zealand is not the place for auditioning any Stax products.

Probably no T2 in New Zealand.

So far quite happy with my self built KGSSHV non carbon version thank you Birgir!
Need another single malt to try! Cheers! Tony.

I have seen original Omega and T2 sold on Yahoo Japan earlier this year, I think. You can order from there via Buyee or another service of your choice, they ship globally. But T2 gonna cost a fortune, and its shipping will cost another.

I've heard the SRM-T2 was to avoid - heat and reliability issues. Is that true?

I may be wrong about this (i wish i could afford a T2!). The T2s that good builders are building these days overcome the problems you've note.

So just to clarify, there's is the original Stax SRM-T2, and there's the community DIY T2.

You don't buy the STAX T2. You build the DIY T2.

Wish we could build DYI Omegas too…

Go read the DIY thread here and there. Chinsettawong and n3rdling are excellent examples of the masterclass.

Hi all, I hope this is the right place to post this (otherwise should I post a new thread?).

I recently bought my first STAX set: SRS-2170, used. I'm not 100% sure whether this was like it from the start or whether it started later but after a few days of owning the set I noticed that it had a rather substantial channel imbalance (have to adjust the balance to L63/R100 to be about even sounding). Also, after adjusting for the imbalance the weaker driver (right side) clearly distorts at times, especially when it has to produce some kind of bass.

Now, I've been reading a lot about this, or at least trying to, these threads are thousands of posts long... But I'm worried that it might be dust on the driver. The thing is, the distortion is more of a "frpppfff" kind of sound (not quite like a STAX fart, but closer to that than to a sharp squeal), not a "squeal" and it certainly isn't constant. At lower volumes, you wouldn't notice anything wrong with the headset 95% of the time (until it hits a bass section) and even at higher volumes it doesn't present when there's no bass. Does this sound like the dreaded dust-got-past-the-dust covers or is it something else, like static or dust somewhere else (which might be easier to fix)?

I'm in South-Africa so any repair will have to be DIY...

Any help/advice would be greatly appreciated.

It could rather be that the right driver has separated from the plate it is usually glued to. Hence an acoustic bypass is made, making it less loud.

Not too complicated to fix, but a labour of love as you have to take it apart, clean it up and glue it back on.

A friend of mine did this and documented the steps (use google to translate from German) - this is what I followed:

Hi there, thank you very much for the advice.

following your advice I removed the driver-housing from the headset and baseplate, and also opened the housing to inspect the driver itself (didn't open the driver itself), but I found that unlike in the example in the blog, it appears as if the SR-207 driver-housings aren't glued to the baseplate, but screwed in. In fact, everything I could was screwed in, even the different plates of the outside driver housing itself.

I unscrewed and removed everything as far as I dared, but did not find any kind of obvious problem. I also inspected the driver-dust covers, and tried to look through the dust-covers into the driver, and couldn't see any kind of blemish, hole, or arc damage.

I fit everything back together and at least I didn't make anything worse (I don't have any experience with these kinds of things), the unit is still (not) working in exactly the same way as it did before.

Well, then that right driver is defective....sorry

Little late to reply, but did you verify that it is the earspeakers that are the issue and not the amp or source? I would do that before tearing anything apart (further). Do you have access to another E-stat amp or energizer to try, or have you tried just reversing the RCA inputs to see if the imbalance stays the same or follows the swap?

And @KDS315, I would not jump to the conclusion that the driver is defective just yet...

A nice KGSSHV Mini posted in the Classifieds.

Don't blink.
