Had my 64F8500 calibrated by Ken Whitcomb from Avical yesterday. Friendly and extremely knowledgeable guy. He told me he was in the 3rd ISF class ever! The calibration took a whopping 6hrs! He said he was having some sort of difficulty with the pre-cal numbers because something was wrong with the profiler on his CALman software. He tried correcting it for quite a long time before finally deciding to "do it the long way. The old school way." At this point he had already been going for hours, but like the consummate professional he patiently worked away until the job was done. I watched a little of the Samsara blu ray to judge how good the set looked post cal, and it looked great, but to be honest, by that point it was almost 3am and I could barely keep my eyes open. I'll do a more critical evaluation tonight and also post the post calibration report.
