As a sidenote, you don't have idea how much tracks from the Anthology are corrupted and clipped ! The "Recording the Star Wars Saga" doc doesn't give the whole statement about ESB. Not mentionning the convertion of the Tomlinson mixes as 2-channel stereo tracks: did you ever notice there's almost all the orchestra sounding on the left with mostly isolated instruments and a far echo of the bunch on the right...? (Looks like it's mainly the left channel wich sounds saturated, wich is clipped and recorded too strong, as it looks to be mostly this one containing the 50hz tone for the film synchro too).

Then I can't sincerely tell if my stereo corrections on the Anthology are a real "restoration", or just a compensation. Anyway, sure it's better and sounds fair.
