WooAudio 2

Does anyone have any experience with the WooAudio 2 preamp? I'm not finding much info on the web.
Have you had a look over at Head-fi (www.head-fi.org). There's a fair bit in the forums there on WooAudio amps, though I'm not sure about the 2 preamp.
Yes...that's where I first heard about them. I'm just trying to find more.
