Just bought this SACD today, and I'm giving it a well-deserved vote of '9'.
Why not a '10'? Simple.
I don't like the drums only in the surround channels throughout the entire album.
I particularly felt like I was getting whacked on the sides of my head during Billy Cobham's solo in "One World", at which point I turned round the other way so that the drums were in front of me. Ah, now that's more like it!
Besides that however, there's not much else to complain about concerning this disc. This is an album made by a band with such incredible and killer musicianship all transferred over from the original Quad mix tapes with no loss of fidelity whatsoever. This really is the best this album has ever sounded, so it's worth adding it in to your collection if you fancy this kind of music.
