OK, I will add my 2 cents to this thread. I have just spent the last 3 hours with my RS1, and comparing the image to my Sharp 20K.
First the particulars of my set up. I am projecting about 22 feet onto a Da-Lite High Power that measures 65x116. My room is light controlled, with all the crucial reflection points painted black, covered with felt, or other dark materials to minimize room reflections.
I have been running the Sharp 20K in High Contrast, High Bulb mode, and it has several hundred hours on it. It is currently putting out less than 200 lumens in that mode. Even with the High Power, I have been viewing at about 11fl. The projector is calibrated with a Progressive Labs sensor.
Now for the RS1. I spent time setting it up, and tweaking it with test patterns on disc, and within my Crystallio 2 processor. I measure the light output on low lamp, at 384 lumens, at my 22 foot projection distance. The convergence is decent, with about a half pixel red shift, perhaps a bit more at the outer edges of the image. I checked the color temperature out of the box, and it is almost dead on at the middle color setting. I adjusted the contrast down about 4 clicks to eliminate some white crush, and brightness down 1 click for best representation of the pluge pattern.
The first thing I looked at was the sharpness. This looks very good. I have no real complaint with it although it is a hair softer than my Sharp. Movies look very detailed and sharp, while also looking smooth, without the digital effect of DLP. I am still debating over which image I prefer from a sharpness standpoint.
The second thing I looked for, was the dreaded "light corners". Honestly, I really don't see it on my unit. There may be a slight lightening of the black bars when watching a scope movie, and a very bright scene, but to me this is a non issue, or I just got a good unit.
Overall black level is excellent, on par with my Sharp. Perhaps a slight bit higher than the Sharp, but at almost twice the FL, this is an acceptable trade off. Fades to black look good, and colors are very nicely saturated due to the excellent on/off CR.
There is one thing that bothers me just a bit about the image, and it is really hard to pin it down, but I believe it has something to do with the ANSI CR. I don't see a haze, like I have on previous LCOS projectors, but there is a phenomenon that seems to happen, mostly in bright scenes, especially if there is a bright background and dark foreground, where the image seems to flatten out a bit, and loose depth. Overall, it is subtle, but this is where the Sharp looks better. There is a real wow factor with the Sharp, that I am just not getting with the RS1, on some scenes, on the other hand, some darker scenes, with bright material, within a darker background, look better on the RS1.
So, overall, I think this is a keeper. I am still on the fence as to which is the better projector. I will try to summarize the pro's and cons, from my perspective.
Incredible ANSI Pop and depth in bright scenes.
Very good On/Off, fades to black in high contrast mode
Rainbows are prevalent for those who are sensitive
Low brightness in High Contrast mode
Very dark scenes have less pop due to the low brightness.
Very smooth filmlike image with decent sharpness
Stunning image in dark scenes with bright objects.
Very good On/Of CR
Somewhat softer image
Slight lack of Pop and depth in bright scenes, especially scenes with bright backgrounds.
That is about all I can think of right now. I look forward to spending more time with the RS1, and will let you all know which projector I prefer, in a few weeks.
