Received a bit of money for my birthday, and while I'm considering some new music, I'd like to upgrade some older CDs as well. Has anyone purchased the remastered versions of Power Windows, Grace Under Pressure, and/or Signals? What's the sound quality compared to the original CD releases? Are they worth buying to replace the originally released CDs? I'm really hoping they are...one of the "for sure" purchases using birthday money is Queensryche's Rage for Order, which from all sources is incredible. Thanks in advance for any opinions you can give.
