I just wanted to stress here to all the home theater beginners the importance of this from a first hand real life story. Calibrating your system properly and accurately is the best way to get the most out of your equipment. The only thing I did when I moved my HT to my new apartment. Was do a quick speaker balance. And basic screen calibration (no convergence). So after about 6 months in the new apartment and a year of being setup total. I decided to re-calibrate everything from the ground up. I reset my room size, speaker distance, and relative volume levels (with the help of test tones and a SPL meter). Re-did my convergence, brightness, picture, tint, color, and sharpness settings in my IDEAL viewing environment witch is after the sun goes down and I can control the light in the apartment to virtually nothing. I also did all my speaker connections, cutting and stripping the new ends of the wires. After a year they oxidized quite a bit. There was a significant difference in both picture and sound quality. I had also moved one speaker in a few feet and added more furniture and wall hangings since I moved in and originally set it up. The moral of this story is to continue to have a great HT experience you should re-calibrate every once in a while. Epically when you make changes to the room.
