I had my audio and video system calibrated by Jeff Meier of Accucal about a month ago (
http://www.accucal.org/). The results are simply amazng. Jeff has awesome skills and very expensive calibration equipment. He definitely knows his way around a home theater. Not only that, Jeff is very friendly and helpful when it comes to answering Home Theater questions. The result is Jeff turned my Kuro into a professional monitor. The adjustments he made to my audio system makes my B&W speakers sound really terrific too.
I strongly recommend the services of an ISF/THX Calibration professional to really dial in your home theater. I also recommend choosing an industry professional and Jeff is one of the best. I am dazzled every time I watch movies or listen to music on my Home Theater.
