List Ultra Dynamic music for testing systems

In my years around the hi-end audio business, my biggest complaint with the vast majority of very hi-end audio gear has been that the dynamic ability has been the "down fall" of most more ambitious and refined speaker systems I've encountered! You play some heavy rock, techno, or other dynamically demanding material through most of these set up's and most often you'll find the sound is less than awe inspiring! That once beautiful sounding speaker, that sounded oh so clear, detailed, transparent and real through the same sysetm, now sounds weak, feable, un-dynamic, and pathetic on anything with "guts" played through it!!!
While there are some exceptions I've come across in the very hi-end, most dissapoint for the "hard stuff" sorry to say(the very reason I'm "a no go" with the likes of Maggies)
My question is, "can anyone recommend some music cd's that have tremendouns dynamics and authority, which will test the integrity of a system dynamically!?! I have found several dynamically challenging music cd's that I like to test sytems out with. If you are currious about what your system can do dynamically(not just deep bass, but mid/upper bass on up!!!!), I recommend the following "VERY DYNAMIC" music to "crank" through your system some time!:

"Absurd" (Fluke/techno)
"Mission Imposible,Gladiator,& Interview w/Vampire
(Soundtracks)
"planet Drum" (Mickey Hart/new world)
"Metalica/Load & Van Halen/"me wise Magic"(rock/metal)
"Mystere" (Cirque de Soleil/new world)

Any other recommendations for very dynamic cuts/records???
