Mercury Living Presence

I have a few Mercury Living Presence label CDs. I've found I have an affinity for what I've heard on this label in terms of recording quality, in particular for the vintage of the original recordings. I was listening to the MLP recording of The Nutcracker recently and was semi blown away.

Does anyone else share my affinity for these recordings? Are they all equally well recorded? Which are the best?

What about the original vinyl recordings, which I have not heard. Are these any good?
