Many good points have been made in this thread. I don't care to debate, just add my own 2c.
The packaging is excellent. Nice book, but I don't care for the plastic buttons that hold the discs in place. I fear I'll break the discs. (Same issue with Porc Tree's In Absentia.)
As for those who gripe perpetually about the sound of Yes, 1972 was 50 flippin' years ago! I'm surprised there's any original members still active from that time (and before anyone barks, I know Howe & White aren't original). The point is that the band is bound to evolve if it is to continue. I got to see the last tour with Squire in 2013. He's irreplaceable. Davison acquitted himself with honors, despite a few morons howling for Anderson.
I feel The Quest is a fine addition to the Yes catalog. Downes, Davison, and especially Howe turn in some fine work here. Overall, The Quest feels like a filled-out Steve Howe album, which I'm OK with.
As for the DTS surround mix, I dig it. According to the book, 4 days were spent on it. It's very good, but not great, and certainly not up to the high-water mark of the average Steven Wilson mix, but few things are. Wilson has spoiled us all. The video backdrop is screensaver quality. Audio is crisp and clear with tight bass. Rear surrounds have plenty to do. Not much in the way of acrobatics, but it's a very good mix and an enjoyable listen.
It likely won't rise to the value of the Wilson remixes once it goes out of print, but it's worth having if you enjoy the band. I gave it an 8. That's very good. I save my 9's & 10's for the real mind-blowers.
