There is an XRCD2 of Hell Freezes Over. Check out http://www.a4audio.com/home.asp
Get the LP. You won't listen to the CD ever again. :-)
If you want a CD to use as a demo, try the Columbia/Legacy "American Milestones" reissue of Willie Nelson's "Stardust" (CK65946)- Or, the Paul McCartney "Unplugged - (The Official Bootleg)" (Parlophone CDP 7964132 - also available in the US).Now there are a couple of CDs you can test your system with. I know everyone likes the opening few bars of "Hotel California" as a demo, but, come on, the rest of that album is really not that well mixed. Great music, average recording.
Just my .02.
