Finally looked at the RS-1 and Ruby together last night. At this point, I've decided to replace the Ruby bulb (currently on 2nd bulb which has 364 hrs) before comparing the PJ's again. Having just read the days posts from other owners, I'll pass on the superlatives, of which there are many, because it has all already been said in these other posts.
I will say this, it was clear to those viewing last night that the RS-1 had the better PQ. Not that the Ruby didn't hold it's own, it did. What I'm wondering at this point is how much of the difference was based on the the hours on the Ruby bulb. I'm ordering a new bulb which will arrive by Friday.
The RS-1's ability to provide depth in dark scenes while still resolving shawdows and not affecting the brighter images in the scene is incredible, and clearly beats the Ruby in this regard (no surprise considering the DI).
A quick example, at the very beginning of Batman Begins, the bats, in huge numbers, are flying around a clouded sky with sunlight peeking through the clouds in the background. On the RS-1, the contrast was excellent, there was a 3d affect to the bats, the image was sharp, and the sunlight was bright. On the Ruby, not as much 3d (but still very good), not quite as sharp (I thought, but others thought the Ruby was as sharp), and the sunlight was very subdued. Likewise, the first prison fight scene taking place outside appears to be filmed with a very heavy overcast sky with the Ruby, which affected color rendition (clothing and grass). In contrast (no pun...), the RS-1 gave the impression the fight was taking place under a cover (overhang) with sunlight striking the field in the background being very noticeable and the color of the grass was a natural green (not muted (dull) as on the Ruby). It will be interesting to see if this changes with a new bulb.
I really cannot see, nor could the others present, why anyone would be concerned with light output. I was projecting to a 127" (16:9) FH, in a room with light colored walls and ceiling (however, I do have 5' to each side wall and 4' to the ceiling) in Normal mode. There was plenty of light. In fact, I would have settled for slightly less light. I occasionally like to watch two films in one sitting and would not want it any brighter. In normal mode, the RS-1 is nearly silent.
OOTB, color was natural to the eye (fabulous colors). No convergence issues at all and blacks were as described by others (excellent).
Corner brightness? What corner brightness?
Seriously, I cannot explain others concerns in this area, but it was/is a non-issue for me and the others present.
We will be taking a closer look on Friday.
