So, for my birthday, one of my boys gave me a gift certificate to Barnes and Noble so I could order some music (apparently, they don't sell hi-res audio formats in their stores).
I ordered Steely Dan's Gaucho on a 5.1 DVD-A and Edgar Winter Group's They Only Come Out at Night on a Mobile Fidelity Sound Lab stereo SACD.
Gaucho pops! It is such a great recording, I can hardly describe it. Great left to right imaging as well as front-to-back. Even better dynamics. It's one of the best recordings I've ever heard (at least on my modest system).
The Edgar Winters SACD.... not so much. After Gaucho, it sounded pretty dead and lifeless. I don't know if that's the fault of the original media the SACD was made from or what. Don't get me wrong, it still sounds pretty good, but more like the sound of a well-recorded CD than an SACD.
