Agree with above. It is huge.
And it's free, and it takes 15 minutes.
Think about it this way...
1) Spend a month or two properly positioning speakers, which should be done anyway
2) Calibrating phase and equialization of each channel depending on the room
3) Another two days to really get it right using ears and an analyzer
Or just press a button. Eitherway, the biggest element in your HT is the room. Second to that is speaker positioning, thirdly your speakers, fourthly the equipment.
The auto-calibration stuff can take a 40+ hour process and make it a press of the button. One would be very foolish to not take advantage of this technology, use it as a base and tune from there.
