I'm sure there is, it's just not close to the same. I have EAX off in America's Army for the Revo 7.1 Sensaura libraries. One of the most obvious differences is on the Pipeline map, which revolves around attacking or defending an oil refinery. With the Aud 2 EAX on, I can actually hear oil running through the pipes. No matter how high (before it reaches the point of causing hearing damage since I use headphones) I turn the volume with EAX off, I don't hear it. That's really big. I think the biggest feature is EAX based on the fact that it's the largest selling point of the chip. Creative isn't pushing the chip onto hi-fi audio people, they're pushing environmental audio on people who play games. The Aud 2 suffers from the same thing a stock Revo did for audio. There is just subpar buffers, subpar opamps and hurts whatever chip each has. M-Audio changed the opamps to something better, i'm waiting to hope Creative one day realizes this too.
