Every once in a while, a component has a decent internal amplifier. You win.

We all knew this was going to happen but I've taken the SR-507 I got less than 24 hours ago apart. Stax does warn about any and all tampering voiding the warranty so don't try this at home kids. First off, lets remove those driver housings from the arc assembly (they just pull out like on the two other Lambda designs). Here are the 507 name plates: Now lest lift up the four corners of the earpads and remove the screws which fix the baffle to the back grill. The baffle just pulls out and we are greeted with this: Now this is very different from the other Lambdas, gone is the aluminum baffle with the driver glued onto it and now we have a molded plastic baffle with a cradle for the driver to sit in. I'm not sure what plastic it is but it is very stiff. Like I said above, Stax warns about the warranty being void if one tries to tamper with the headphones which would explain this: Now this just confirms what I thought as soon as I opened up the headphones, the drivers are not glued together but rather just stacked together inside the shell. This is how the SR-Omega is assembled, also the SR-007 and the SR-003. Throwing caution to the wind I remove those 4 screws: Here we can see the silicone o-ring used to seal the back of the driver and the new chrome look of the metal plate used to hold the dust cover in place. Now it's time to put my hunch to the test and see if the dust cover is glued to the stator: Indeed it is not though there is some compound used between them. This gives us a direct view of the stators which appear to be coated metal plates, similar to the newer stator design introduced in 1994 with the Lambda Nova Signature. Since I don't happen to have a clean room to do stuff like this I tried to keep the drivers uncovered for as short a time as possible. There are glue pads on the end of the driver so I decided not to mess with them and try my luck exposing the diaphragm. From the side view offered where the connections the diaphragm is still mounted to two solid brass rings like on all the other Lambdas. Now we take a look on the other side of the driver. With the new earpad design this is quite simple, just use a knife to lift up the cloth cover and you can see the protective mesh: This is the same silver colored material found on the post 2004 models. The arc is also new and very substantial if a bit uncomfortable for somebody with a gigantic head like me. They need a lot of parts to make this one work and plenty of screws. None of the cost cutting seen in the post 1994 arc assembly here. Now they are back together and needless to say, they work perfectly.

A wizard did it.

Sell your WA6. And also who cares.
