At the opposite side of the spectrum, the Onkyo pro and Integra pre/pros with Audyssey MultiEQ retail for $1,600 - $2,000. That makes me think the Audyssey processor is not the determining factor in the price differential.
Here's the difference directly from the manufacturer:

Notice how the high end versions use more measurement points in the room. Also, notice how the filter resolution changes. Basically the more advanced versions have more bands of EQ that can be used to tweak the signal further.

Hope that helps.
