I'm also looking at this product, to use for home recording and as a CD transport to feed my Theta DSPro Basic IIIA DAC. I understand that the single-well version, the CDR631, has a better A-to-D converter for recording LP's. I haven't been able to demo these, so any knowledge or experience with the units would be appreciated. As for the duplicating project mentioned above, I would imagine this unit could do the job as well as any such product short of a real multi-drive duplicator. A studio owner did comment to me recently that his experience with heavy use of players from this brand seemed to result in earlier or more frequent failures than Sony or HHB, for what that's worth (he didn't like Fostex, either). The feature set on the Marantz seems most attractive to me, however.
