Spectral DMC 30 SS

Does anyone have the details for the 2007 DMC 30 Studio
Standard preamp? Is it just a DMC-30SL.2 or is it something newer?

I've heard it's a replacement (advancement?) over the 30SL, based on some future "40" model prototypes?
The latest info on the Spectral DMC-30SS and the HDCD Long Filter for the SDR-4000S is listed under, Spectral Audio Bulletins.
