The design of this has absolutely nothing to do with me having Quad ESL57's and a new big living room...

Most excellent.

Some internal pics wouldn't hurt... We can see pretty much what is going on but it would be nice to be sure.

That's so fucking true that it isn't even funny. Danish is impossible to understand let alone speak.

Just as small heads up, I've extended the sale until midnight on Tuesday to help a couple of people. Also makes sense to let it stand for a week.

When Stax did 100V only amps back then they just wired the sockets every which way as they were never supposed to be used with the plug. You need to completely match the picture above but it looks like you are lucky, just move the green and brown to the their correct spots and add the other white wire. Just make sure it is the right one as Stax always used two white ones for some reason. Hehe I'd say most on HF wouldn't call us nicer but welcome. Here we talk about the stuff that actually matters, not the stupid crap HF calls a Stax thread these days.

DIdn't we call them Mk2.9 or something like that but yeah, very latest version is great. Serial numbers can't be used to see what version they are so just get a new 007A from Japan.

Yeah I'm not sure if I want to become any more famous. My friends googled me once and saw me pop up in strange languages all over the world. Still we need to spread the gospel a bit further as a 727/009 isn't top of the line as some might think. Part of that plan is the rebuild the Unofficial Stax Page with info about all the Stax headphones plus other electrostatics.

The LED's are not a good way to troubleshoot the amp. Tubes being lit means nothing, the heaters are just pilot lights really. To actually troubleshoot anything, start checking voltages.

Yeah that helps.

I'm not sure I ever want to become a "brand"... As for the 009, I don't think that they were designed for the amps in mind. In fact that would be very unusual for Stax. It's much more likely that they got caught up in the new toy fever of the diaphragm material. That and their measurement equipment was just not up to snuff.

Did you alter the springs on the headband? I also didn't touch the earpad springs on the new ones which helps minimize the farting...

The difference is quite large. The new ones are ok without the mod, the earlier ones really weren't.

Water and high voltage... yup sounds like a plan...

Yup, that should be 450V.

Not sure yet but this is Stax, they always release a fixed version. I'm half joking but also been burnt enough times to not get a first of anything from them.

We always specify loaded voltage. If it rises much above that (plus line variation) then the caps would be in trouble.

Sure, there are also people who think the WES or the LL are good amps. Doesn't mean that they aren't bad though. The bottom line here is and always will be, what is neutral. That's what Stax have always been about aside from the whole Sigma stuff (though neutral in their own way) but the SR-009 simply isn't. It has a definite sound of its own. This is the same with the HE90 vs. HE60. One is highly colored and limited by design while the other is just limited by design.

Gotta have some Blue Hawaii's...

That would be excellent!!

Gotta be a part of the groupthink, perish the thought of having ones own ideas. Seriously though, Purrin is no better than Jude with his clan mentality and favoritism. As for the Stax, haven't tried the L700 yet (waiting for Stax to release the inevitable fixed version) but many of the older Lambdas are excellent. I've recently bought the SR-SC1, 404LE, 404 (why not) and Lambda Nova Signature. All of these are good to excellent and if you can find a set in good nic then it will last for a long time.

I don't know how Kevin does it. I've left HF for good and couldn't be happier. There is soooooo much misinformation based on no shred of truth. As for the Big Sound, I'm sure Bob and Tyll would have reached the same conclusion with any capable amp. Even the Carbon can't save the 009 being the most powerful and linear amp we can build. Edit: Well Chang2.0 would have to access to some brain matter before anybody would take them seriously. That sadly is lacking...

Thanks guys. It's a nice part of town, right next to the presidents residency. The LNS doesn't care other than the amp is more powerful but it's been a while since I've had a HE60 here and they can be tricky. Perhaps the KGST or KGDT to soften the top end a bit and flesh out the bottom end. I'm just guessing here as I haven't tried the combo.

Voltage and current are inherently linked and I already covered why we use higher voltage. Headroom Other than the new portable amp which is finally something from this century there is little to be excited about from Stax. While on this topic, I checked out the HF Stax thread yesterday and holy shit the retardation is strong over there. I mean seriously, the level of stupid ignorant crap is just astounding. My favorite bit of utter stupidity was Tyll's amp turning the 009 into the 007Mk1 so it's use should be discontinued immediately. It's not like the amp wasn't measured directly against a BHSE using a 009 when Tyll got it with nearly identical graphs (well within the margin or error)...

The Octave is the warmest of the bunch. Traditional tube amp in every sense of the word but with some clever stuff thrown in the mix. The KGDT and KGST are similar as they are based on the same design. The DT is a bit warmer due to lower voltage rails and the tubes used. The ST has this slight warmth to it which suits the 009's to a T. Helps with some of the upper midrange nastiness they are prone to bring.
