I second The Steely Dan Gaucho. What I have found is understanding the many types of SACD helps. Also that not all SACD's are created equal.(Journey Sounds about the same as the cd version) So ones that I found that made a huge difference are in this list that when played on SACD in surround really caught my attention:
Fleetwood Mac Rumors
Dire Straits Brothers in arms
Eagles Hotel California
Moody Blues Days Of future Past
Stevie Ray Vaughn The Sky Is Crying
Pink Floyd Dark Side Of The Moon
The Doors - L.A. Woman
Yes- Big Generator
Yes-Fragile
Chet Baker Bakers Holiday
Miles Davis Some Kind Of Blue
Miles Davis Bitch's Brew
Donald Fagen Nightfly
Marillion Fear
Alan Pasrsons I Robot
Jazz at the Pawnshop
Dimeola,Mclaughlin,Delucia One Night in San Francisco Not Multichannel but amazing
