I also switched to high lamp mode at 300 hours on a 120 inch stewart 16:9. I now have a brighter image and the iris mainly closed on the 66.
The presets seem to be a bit more accurate and I also picked up the auto calibration function. Highly recommended.
In the UK the price differential between the RS56 and RS66 is 3000 UK pounds. That is over 4500 USD! These two projectors are identical other than the contrast ratio. The contrast ratio of the 56 is 90k:1 and for the 66 it is 130k:1. That is a bit under a 50% improvement in contrast between the two which sounds considerable. I have the RS56/X70 and it seems to be outperforming its spec...not to RS66 levels, but about half way between an RS56 and 66 official specs (according to my Sekonic light meter). I got lucky there.
I doubt anyone has been able to do this, but if anyone has side by side compared a 56 and 66 I would love to hear about it. Although the contrast ratio is better, it is the law of diminishing returns. You will see more of a visual improvement going from 30k:1 to 45k:1 than from 90 to 130
You mentioned the auto-calibration capability. Have you actually tried it? I played around with it and it scared the hell out of me to be honest. The instructions keep warning you that it over-writes something inside the projector and you better keep the back-up file the software creates otherwise you can never get the projector back to factory defaults. I honestly don't understand what the scaremongering is about. Yes you can over-write the internal presets with this software it seems. But we know that the projectors are NOT hand calibrated at the factory. They are built within ever increasing tightening of the tolerances as you move up the range. So what is there that you can over-write and never get back? Surely if they are all the same you should be able to get a re-initialization data file from a download site. Unfortunately this clever bit of software seems to have had so little use outside of Japan, that nobody seems to know what its doing behind the scenes.
Anyway I played with the software, saw that it does cover gamma, greyscale AND CMS. Saw that you could over-write the initial presets. Saw you could create your own colourspace definitions. Tried a couple of calibrations...got nervous and then uploaded the factory init file that the software created the first time I did a calibration. By the way, this software is primarily aimed to defining presets, and not performing an end to end calibration. The software wants you to have the meter facing the projector and NOT the screen material.
