Recommendations discs for SACD/DVD-A trial

Well folks, I'm going to give hi-rez a chance (2 channel, wouldn't want to rush into things). Can anyone recommend a typical and a superb disc that I can buy in both redbook and hi-rez to use to try this out? After reading the latest S'phile article about the Norah Jones SACD being mastered from the redbook digital files and not the analog master tapes, I would like to give this a fair trial. So I am looking for something that is representative of what hi-rez 2 channel can bring to the table, and something that is the best there is. I would like to buy redbook and hi-rez
versions of each of the two discs, so I can put one in a modded Denon 2900 and one in my EMC-1UP SE. I'm not a big classical, rap, metal, or hip-hop but otherwise, I'm open to many musical genre's. I'll be sure to post the results when they are available and would be happy to host some NY/New Englanders at my place in CT for the trial. More details later.
