Christmas CDs

Just listened to Christmas CDs. First Christy Moore "This is the Day". Very good indeed, the best he as done in ages. Then the Beach Boys "Carl and the Passions/Holland. Music wise this is a great double CD. Holland really is fantastic considering it was 1973!. It's a new digitally remastered 24bit CD whatever that means but still sound quality wise is disapointing. I am thinking of getting the other remastered Greatist Hits CD, is this the same sound quality? Can anybody help here. If so I don't think I will bother. Any other views on the sound quality of the Beach Boys CDs? Specially the latest digitally remasted ones. I know there has been umpteen threads in the past about the Beach Boys, but I think an update is in order.
