Yeah I have seen the Imperial Edition, which by the way is the most completely kick-ass orchestral movie experience I have ever encountered. I'm not suprised there aren't lossless or uncompressed sources for the EditDroid set. I have been working on collating lossless sound mixes for the OT and syncing them for the many great projects here, and everything except for the Isolated scores (Theatrical, 85, 93 and commentary mixes) is available in non-lossy formats. If there were ever Imperial versions done for SW and ROTJ I would be amazed, as the quality of the ESB one is mind-blowing (although ESB also has the best score IMO).
