I also use Sheffield's Drum Record, especially the side with Jim Keltner. Compare your listening experience with that of the liner notes. If your system doesn't match up, then, your system has a weakness.
I also play Mozart's 2 piano concerto. If I can clearly identify which piano is playing, that is the better piece of equipment.
