I'll help bump this thread! I haven't put these on cd yet but playing them on the the computer over optical to my stereo (Polk towers, not true hifi but pretty good, and excellent AV123 subwoofer), I am in love with the sound quality. Definitely a big step up from what is on the official versions, particularly noticeable on Jedi.

When making my custom OT dvd's, I inserted the deleted music from Luke and Ben's conversation on Dagobah in Jedi back into the movie soundtrack, and used the ABC set as my source. Used the Izotope algorithm to resample to 48 khz, and it sounds completely awesome. Thanks ABC for doing such a great job on these!
