I have done a quick test with QuickTime 7.6.6.
Sadly there is no improvement with pre-echo artifacts:

Both encodes have a disorted artifact at 0:30 - 0:32, which sounds too obivous for me.

Heavy distortion at 0:18, due to pre-echo.

The 2009 remaster also contains the artifact, but it sounds softer and is at 0:19 - 0:20 this time. Please note that the old mastered version got overwritten with the remastered track after i ABXed it.
