...Go rent
Master and Commander and play through the opening naval battle. Crank it up. If the pounding of the cannons doesn't knock your socks off, then something is wrong with your setup.
You beat me to it. Most two-channel music is probably not the best way to show off the power of the EP500. I'd be curious to know your impressions after watching/listening the battle screnes in Master and Commander. Also, I am not sure if it has been mentioned or not, but if you room is not large, I would set the sub setting to Full and see if you like it better.
