On the Stax thread(new) I saw rumblings about this earspeaker from Stax called the SR-507.  I tried to research but, surprisingly, there is little information on them other than basics.  Supposedly they are due in September, 2010. 
 
I wanted to start a thread in order to collect any and all pertinent information that people from head-fi have.
 
Thanks and I am loving my 4040II Sig System and wonder how this new earspeaker will measure up.

Thanks nikongod, I've never used the translator from google...it's quite good.
 
Paaj, thanks for the link to the translated, too.  Wonder if these will sound any different due to the following changes, it is stated:

This sounds like a whole new sounding earspeaker.  I like it!

It's decent, but most of the time I find I swap back to the original because sometimes the translations are so bad that you can get the complete opposite meaning from the sentence such as "10kHz at the University including cables" when it is just 10kHz at the attached cables.  Or the bit about the new headband (the original doesn't say "hear," it just talks about the use of the dual arc structure while, once adjusted, will always hold that position to so it'll be soft on your ear for comfort during long listening periods).  But I guess you can figure most of it out from the translations.
 
That said.  These look nice and I look forward to them.  I hope I get to read a few impressions of them come September.

seconded.
-Team I don't want to buy another headphone

The drivers are completly new (the SR-404LE uses the same basic driver frame as the Lambda Nova Classic/Signature, SR-303/404, 4070 and SR-SC1) so they could be something special.  Needless to say I will be getting a set...

 

[monsieurguzel]

Yes, these do seem very interesting.  From the photos the frame looks pretty similar to the 404s but with some minor tweaks.  However, there is mention on the Stax website that the drivers are encased in a more rigid resin enclosure...which has me hoping that there is less frame vibrations when playing lower octave notes.

 

[edstrelow]

Looks like it has the 404 LE pads and cable, but  a different arc assembly and a more rigid mounting of the drivers.There is an indication of a different driver material but they are pretty coy about describing it. 
 
Most of the specs however still look like  a 404.

I suggest the Stax SR-507 English page.

 

[Region2]

jjnh but now you took all the hard work out of it 

 

[tvrboy]

This is good. Stax really needed something between the 404 and the 007. Hope it's not as hard to drive as the 007.

 

[Uncle Erik]

Very interesting - I might have to pick up a pair of those.

 

[n3rdling]

Will be interesting to see if this becomes the best of all Lambdas.

 

[edstrelow]

The Lambdas have one basic advantage over the 007, as far as I can see, namely that they have  a fully open back, unlike the the quasi chamber behind the 007, which in my opinion causes coloration and a compressed soundstage.  So if Stax have successfully addressed the problems with the Lambda by coming up with a more solid earcup and driver mount they may very well improve on the 007, especially if th driver is itself improved.
