any experience with pro ject usb phono amp or turn

I have an extensive vinyl collection and would like to know if anyone has any experience with any of the new phono preamps that include a usb connection. I've duplicated a lot of my vinyl with the same cd's and think it would be better to just download to itunes or other. Any help would be appreciated.
not quite the answer you were looking for but see Michael Fremer's report on Project Debut III USB equiped turntable for an idea about how the usb phono will work.

Can email you the transcript if you don't have may 2008 issue of stereophile.
