Summary
Perhaps the most significant thing I can say about the JVC RS1, is that, as things stand right now, the RS1 is at the top of my list to replace my 720p BenQ PE8720 projector in my theater.
Although I haven't made my final decision, and may not for a few more weeks, I have no doubt that I will , thoroughly enjoy watching it in my own theater room, and be dazzled by it or a long time to come (a year or two - I do need to stay "current").
The JVC RS1 is certainly a great projector for movie "purists" on the hunt for the ultimate in picture quality. At the same time, it seems to look good on just about everything I have thrown at it. Even watching Boston Legal, or parts of the last Superbowl, which I have permanently stored in HDTV on my DVR, looked great!
Like other projectors, there are features (and therefore benefits), that could further improve it, such as those I mentioned (more brightnes in brightest mode, perhaps a slight bit sharper, etc.), but overall, the RS1 produces such an exceptional picture, that few will find reasons not to choose the RS1, if their budget allows.
In the past LCOS projectors (like LCD projectors) have never been known for particularly ood black levels, one reason why the Sony Pearl, for example, relies on a dynamic iris to generate excellent black levels. JVC, however, with the RS1 has apparently come up with a way to dramatically increase the contrast performance of the LCOS (D-ILA) chips.
The JVC DLA-RS1 not only earns our Hot Product Award, but seriously raises the bar, for future 1080p projectors. I would have to say, that had the RS1 been the first of the "affordable" 1080p home theater projectors to ship, instead of hitting the market about 5 months after the first (Optoma HD81), I suspect there would be a few less Hot Product Award 1080p projectors on this site.
Congratulations to the team at JVC, that developed the RS1, for bringing to market what I consider a breakthrough projector. It not only has exceptional performance, but manages to combine it with one of the most versatile projectors in terms of ergonomics and room placement. Although an expensive projector, it is worth every dollar!
