So I bought the Diana Krall Love Songs album 5.1 DTS version,...I tried to find the other albums with no luck

Aaaaaand....

1. All my CDs sound bad or not so good to me now, even my Norah Jones CD..which I thought was pretty good.

2. What is 5.1 DTS? It's not SACD, my player can't play SACD. It's not DVD-A, since I can't play it through my analog cables. Is this a CD technology of some sort? It sounds SO, SO good, as good as my Blue Man Group Complex DVD-A to me...

Ahhh....I'm buying ALL of Diana Krall's stuff. As one poster said, her voice is made for Axiom speakers...
