Reference/Test Cd’s

I was wondering what cd’s others are using to evaluate upgrades to their system.
Here is what I use…

Foreplay – Elixir Tracks 1, 3, 4, 8

The Rippingtons – Brave New World Tracks 1, 3, 6

The Benoit/Freeman Project Tracks 2, 4, 6, 7
The soundtrack from SNEAKERS is good for setting up subs, recommended by Sumiko. Bass drum being hit repeatedly is good for positioning subs.
