Looks nice! Isn't a TS member running one of these aready??
I started running the USBPre(1) back in 2001. It was very light and felt cheap, which is odd for Sound Devices. I liked the pre-amp, but ended up only using it as a Coax>USB converter. It powered off of the USB port, iirc. It also was limited to 16bit, I think.
The USBPre2 looks a lot better. Glad to see that they realized that they could do better.
