Today I received the new remastered edition of this classic, with the two versions: stereo remastered in 2004 and quad to stereo mixdown done in 2012.
The stereo mastering is excellent, better to my ears from what was done in the triple Cd called "Think About The Times" and livelier than the gold Audio Fidelity version.
But the revelation is the new quad to stereo mixdown. It is simply stellar. With conventional two speakers, instruments and voices float around you with cristal clear accuracy. Obviously some kind of phase shift was done, but the results are incredible. At the end of "Here They Come", the guitar surrounds you like having four speakers instead of two. The best holographic effect I've heard from a conventional CD.
So the music is first class, and the mastering top notch for both versions of the album included in one CD.
Don't pass it by. It is that good.
