I especially like hearing the sections that are supplemented with 7FN's LP transfer. It is fascinating to hear the extra flute, synth, and vocal parts that seem to have been left out of the other versions, not to mention the added clarity of the mix in general.
After those, most of the tracks that came from the RSO cd usually sound the best. It's funny how review sites tend to favour the SE's as having better sound quality than older releases, when clearly that's not the case.
