The Imprint processor uses a researched algorithm to produce what the President of Alpine believes to be the most prominent choice, amongst every day people, for sound. He put together some specific sound curves and did a/b comparisons with groups of people.
This is the curve that the Imprint systems are using as a standard for tuning response. It will reveal a few choices after going through the install steps but they're all very close in approximations. In the end, many installers have found ways to massage their own specific sound curve by creating their own instructive placement of the Audyssey microphone. In the end it's all trial and error with the Imprint system.
If you know absolutely nothing about sound or tuning it will get you closer to good SQ than you'd ever manage by trial and error. It probably does a better job than most local sound shops too. However, if you want to enlighten yourself with books and some research, you have a chance at tuning your ear and possibly getting that much closer to the realization of sound goals.
