when you do a curve copy you have to press EQ button on the remote while listening until it says 'manual' to hear the adjustments. If the screen shows 'audessey'or'audessey-flat' then you are listening to the standard audessey curves, even if you have made manually adjustments to the copied curve.

This allows you to compare your adjustments to the audessey eq to no eq at all.

I found that the brief silence when switching between these made is hard to make a good comparison though.

make all of the adjustments you want on the curve copy since it won't effect the original audessey results.
