The tapes of the original albums were provided by Abbey Road, where they were transferred to high res masters. They were then given to Universal. They decided in the end to boost the levels of the early albums for the CDs as they were so much lower than anything else released in the last twenty years. Don Bartley then ran it all through his gear to give it more body. Neil might have been involved with that too - I'm not sure.
The vinyl was mastered from the same hi res masters but without the processing done for the CDs. Not sure if Intriguer and Time On Earth are new cuts or the same as the originals.
That's a bit sneaky. The press blurb said that the albums were mastered from the original tapes. Strictly speaking, that's true, but in the strict sense, that's true of most modern albums. The fact that they made a point of it suggested that the vinyl had been mastered directly from the tapes.
Am I right in presuming that the "processing done for the CDs" includes the level boosts? That being the case, the vinyl would be the way to go for anyone wanting a warmer mastering without the loss of dynamic range..?
