ELO and the search for SQ

I like ELO's music! But the quality of my 3 cd compilation of their music (Afterglow) has always disappointed.  The recordings are really lackluster. Then I came across an ELO song on a 70's compilation cd and it was gorgeous - clean and detailed and dynamic. So now I'm on the hunt for quality recordings of their music. Even though I have a VPI Classic 3, my preference is to go digital (I'm getting lazy). Will the digital downloads from HDtracks or Acoustic Sounds give me the SQ I'm looking for? Are the 192/24 downloads worth the extra expense over the 96/24 downloads?
