I have a Velodyne DD-15 that has the EQ feature that also displays the EQ and frequency curve on your TV and allows you to test various phase, polarity, contours, volumes etc to blend with your mains. It would have been very difficult for me to have done it by ear alone and the mic and software is very accurate.
You can do the set-up for each of 6 presets (ie, music or action movies) which I find useful and for say music set the servo to produce the least amount of distortion.
After this is done, you can also put on a music or movie source and let your ear be the guide to 'is it seemless?' and still watch the frequency curve on your tv and do any tweaking.
While all this took a while, it was productive in the end. Needless to say, I like the DD Velodyne Series. The DD-15 and DD-18 have the least distortion.
And to answer you question directly, its internally EQ and other set-up features that yuo can see on you TV were invaluable.
