All of the Rush remasters up to "A Show of Hands" were remastered in 1997(from the first album up until "A Show of Hands). I have them all; and have to say they all sound very good. The albums that followed,such as; Presto, Roll the Bones, Counterparts and Test for Echo, were remastered in 2004, and these also sound very good as well. Vapor Trails; it sounds good to me, but a lot of people don't like the sound production of this album.
I also have the Mobile Fidelity version of Permanent Waves. It sounds very good also, but not too much better than the 1997 remaster. What's nice about it is the packaging. It's packaged in a mini-LP sleeve like the original vinyl LP was, which is kind of cool.
