Listened to this a few nights ago for the first time... great collection of songs, really good quad mixes, and mostly great fidelity. I wasn't thrilled when this was released, being a collection of singles (I really wanted the entire B.O.C, Santana and Harry Nilsson albums), but since I've started listening to surround tracks rather then entire albums, I've realized this kind of album is fantastic! Quite often on the old quad albums there might only be one or two songs that I want to hear, and this is a great way to get those songs! And the ones they've chosen for "The Collection" are generally winners (yes, I could have done without the few songs that have already been released on SACD, but whatever). Among the songs never released previously in hi-res, the only song that was a little lacking in fidelity was "Grazing In The Grass" (not one of my favorite songs, either, but still a good mix). I really wish we could get a few more "collections" like this one! 3 for the mixes, 2.5 for the content, and 2.5 for the fidelity. 8.
