I just picked up a "remastered" copy of "Caress Of Steel". Although I haven't done any waveform analysis of it I am quite sure there is no nasty peak limiting going on here. Rush to me always had a great warm analog sound. Rush is certainly one band who shouldn't need gimmicks to sell their music. They already have a huge fanbase, so what would be the point of cramming the level to the ceiling on "Vapor Trails"? It seems silly. (I haven't heard that one myself however)
What bugs me is that remastering is used as a selling point and I have to wonder how many people really know what it means. They plaster it all over the CDs as if to suggest it is automatically better than the older release. I noticed Apple's iTunes has a lot of albums tagged as "remastered" without really explaining it. How about "Louder, With More Clipping!"? That'd be more accurate. "Now More Fatiguing To Listen To!"
Most of the time I can't tell the difference although on some CDs the remaster sounded worse! "Remastered" has become just one of those meaningless marketing terms like "new and improved" it's just peripheral blather that nobody really understands. Might as well just say "Buy It Again, Assholes" on the sticker.
