When I recently went to three different shops to compare speakers, I made my own mix, because it doesn't work too well to listen to a single CD that you're not as familiar with, or may not even like.
I figured I should put a good range of stuff, from old to new, light/spare to heavy and dense. Songs that I know inside and out. I'm a total music geek, so I actually made three CDs. I was embarrassed to whip out the third, so I just used the first two. I also brought a Cornelius 5.1 DVD.

It would be interesting to see others post their choices here.
