Just bought the 3 box sets and fell off my chair when I heard the quality of this work. What a great, great production work this is. So far ahead of the sound of the 90's CD edition with AAD written on the back. These albums now sound bigger, louder and with more brilliance to the whole sound. The stereophonic remixing of this wall of sound that is the one and only Rush sound, is simply of the highest quality i've heard in a long time. Feels a bit like listening to an old vinyl. Just tremendous re-work.
