Re SACD, the proof is in the pudding. I pulled out an old Sam Cooke SACD ( Portrait of a legend) last night and boy did it sound great. While I do have a few cd's that sound as good, it is a joy to hear older classics redone in SACD. I would put the Stones, AKUS, Elton John and even Junior Wells into this grouping. I know everyone is into streaming these days but if you have them, pull out a few you haven't listened to in a long time - you will be in for a treat!
