I don't usually post but I have gotten good advice from this forum and I would like to share my calibration experiences with Jeff Mier from AccuCal. It was based on references here that encouraged me to contact Jeff.
Jeff came by my house this past Saturday and over the next 4 hours, he tuned my 60XBR2, HR10-250, PS3, XBOX360, and audio. Every input was tuned and tested. I was very impressed with Jeff's commitment to getting my system looking and sounding it's best.
Jeff's professionalism and capabilities are well documented in these forums. I understood what type of product I should expect from a technical perspective and Jeff did not dissappoint. I am very pleased with the picture. I think it's got a POP previously lacking. I am also very content knowing I've got the best picture possible on arguably the best product in the market that I can afford.

In fact, it's Sunday night and I've been stuck watching my 'new' setup since Jeff left.
I also had Jeff calibrate my audio and the improvement has been just as dramatic. Jeff was able to get my sub in phase and leveled with the other speakers. All my gear is in a family area and in a corner as well. My settings had the sound muddy and boomy. The sound improvments are just as significant as the video.
I am very pleased with my experience with Jeff. Besides everthing you would expect from a calibration, I found Jeff to be willing to share his experiences and knowledge. A great experience and one I will highly recommend.
Thanks Jeff. You provide a great product and educate at the same time. Bonus.
