I'm thinking of joinging BMG and getting some Miles CDs. I was consider the following: Miles Davis All StarsWalkin' Miles Davis QuintetRelaxin' With Miles Looking on Amazon I see they are available in a 20-bit digitially re-mastered form. How can I tell if the ones at BMG are the same? I've written an e-mail to their customer no-service about this but that prospect seems dim. Anyone know how long ago the digitally remastered version came out? Was there an earlier version? All help appreciated.
