Thanks to both of you for the info.

I currently own an NW-E005, and not long ago I finally got around to ripping my CDs into Atrac. Next week I'll be scoring an import NW-E016 from a Japanese eBay vendor. I'm unclear about whether or not Sonic Stage actually ties a license to each track, so that only one device at a time is authorized. Can I just transfer my current Sonic Stage library into the E016 without worrying about what's on the E005, or do I have to de-authorize/clear the tracks on the E005 first? I had copy protection turned of when importing tracks. TIA.
