I was not aware that Jason had "published" any CR numbers for the 11S2. The fact that he no longer publishes CR and lumen numbers is unfortunate. The AVS community is missing a very important unbiased and objective source of information that a lot of us held in high regards.
HHF, Jason had not "published" the numbers but since they were taken from my unit I had the numbers which I shared. 8)
I know its convenient for some to point to his numbers as some type of "blind test" to substantiate their numbers, when its convenient, just as its easy for them to dimiss his numbers, or integrity - if you can believe that, when it hurts the arguments they are trying to make.
One thing is clear though, people who have seen these projectors in the same room, in the same environment, on the same material, seem to repeatedly support Jason's measurements and conclusions.
Jason still likes the SIM2 projectors. As he has noted on other theads, however, he doesnt believe that they are the best of the bunch anymore. It probably wont be long, but Im sure the time will come for the 11S2 to have step aside in Jason's eyes, too.
Someday, something will come that will knock the RS2 off of Greg's pedestal, too.
I recall reading years ago that InFocus was increasing the lamp power during the red segment and then maybe a year or two ago that Marantz was doing this. What some of us are thinking of is dynamic dimming or brightening based on scene content that is more like a dynamic iris, as far as increasing CR in a way that isn't native CR. Pushing the power within the red segment falls within the native CR IMO, but lowering the power to the lamp because a scene has an APL of 10% doesn't. There may also be cases where the line between what is native CR and what is dynamic CR gets blurred.
The specifics of how lamp pulsing/modulation increase brightness/CR/etc are interesting and it does seem that they do bring the benefit of a higher CR and a brighter simultaneous image. These benefits, though, do come at the apparently documented expense of at the minimum a greater propensity for rainbows and the scene to scene shifting of color/skin tones.
Its fairly recent history and Im sure everyone is very familiar with the reports of greater incidences of rainbows and of others turning off brilliant color on other machines because of the colors shifting.
As far as color accuracy goes, wouldnt shifting colors because of lamp pulsing actually shift the colors on a scene to scene basis? Wouldnt this color "shifting" actually hurt the color accuracy of the image?
If you fix colors with a CMS with the lamp at a certain level of brightness wouldnt you again have to shift it every time that it modulated for it to actually be as color accurate as possible?
There are some remarks from Bob Williams, with Planar, on some of the negatives on the Planar threads.
Regardless of the benefits, negatives, measurement techniques and instrumentation used one thing that is clear to me is that in Jason's setup, same environment, etc, in iris 3 the 11S2 has similar brightness, actually brighter, than the HT380 and has similar black level (hence his comment that the CR was similar, around 5500 or so) and does not need lamp modulation or a dynamic iris to achieve it.
