After my newly installed 56 was not able to be programmed with accurate lens memory positions, I was told that a replacement would be worked out. My set-up is a little unique; 140" 2.40:1 CIH Carada BW Masquerade system and new projector installed further back on my ceiling (dedicated, light controlled theater). The 56 would be replacing the very fine RS 35 from 3 years ago. The new projector performed perfectly, except for the memory function (would return offset to left every time, about 3 inches) not using an anamorphic lens was a choice based on what I had seen in several demos over the years of both methods. Was set on A lens, but realized that if necessary, I could always add that later. I'll admit that a new projector with 3 more years of development, 3D capability and the afore mentioned lens memory function were all factors in my decision. I spent a weekend calibrating to my taste (with DVE disc) and got all the settings just right. Picture looked wonderful. But when you blow- up something that big, several things become very apparent; first, the light output was better than expected and very bright. Noticeably brighter than my 35. Second, while the eshift 2 function works well, it does not work miracles. Nor does it seem to add artifacts, to me it makes everything smoother. Colors were fine (not my most important element) but putting on widescreen movie after widescreen movie, I wanted more resolution. If I had stayed with my 110" 16:9 it wouldn't have mattered, but with my replacement arriving soon I wondered if the RS 66 would make a difference. Long story short. Wow! I now own it, will spend a long time paying for it, but to me, it is absolutely worth every penny. Just as bright. Darker and lighter at the same time, but the capper is the extra resolution provided with better lenses due to only using best parts. It somehow produces enough extra detail to make everything look that extra bit sharper. I went back and watched all the usual Blu-Rays that I had with the 56, and the difference is very noticeable. Edges are more refined. The picture seems effortless, like it should cost about a third of what it does. Anyone considering the size of screen I now have, especially coming from a smaller screen, you will not be disappointed. ISF calibration will be at the end of the month, and I reserve my final judgements until then, but this is a winner for me. Oh, and did I mention I used to own a Sony G70 CRT , this gets as close to that level of blackout I have seen so far. And the 3D is quite good. Yes, occasional crosstalk noted on titles and various times during certain discs, but it is very well done. The glasses that were included work a smidgen better than the Panasonics I got on sale. Anyway, for anyone looking for a great projector, either of these are excellent, but the 66 is king, at least until 4K, or thereabouts. Just my personal opinions, please take them with the grain of salt that they were intended and I'll report after my calibration. Many thanks to Jeff at TheaterExtreme Richmond for all his help, they are wonderful people who get my obsession for a great home theater experience. If you live in mid-Atlantic region I highly recommend them. Very happy now. Hope this helps anyone looking for this kind of setup.
