I say a 10 because it is simply one of the best albums ever created. Raw, entrancing music; lyrics that are by turns hilarious, mysterious, ecstatic, and sad. The songs convey a sense of the glorious, tragic mess of being human. And those amazing, plaintive voices! Danko, Helm, Robertson, and especially Richard Manuel.
The surround is very good given the limited number of tracks available for the mix. Major hiss at the beginning of a couple of cuts happily tells me DNR was likely not applied. Even with the new surround, the spirit of the late 60s stereo LP is solidly present (unlike the cleaner, more modern flavor of the recent 5.1 Blu-ray).
The Band's second album (the self-titled brown one) is wonderful and considered by most critics to be their best, but Music From Big Pink -- which I bought on its release -- will always be my favorite and have a special place in my heart and memories. I simply could not score less than 10.
