Best of Class: JVC DLA-RS1 LCOS (D-ILA) home theater projector
I'll keep this short. The JVC RS1 is a breakthrough projector in overall performance. It's not cheap, but it is worth every penny. Thanks to re-engineering the LCOS design, the RS1's D-ILA chips (LCOS) produce contrast ratios unmatched by any other projector, whether using LCOS, LCD or even DLP. This is huge, as LCOS was, like LCD, considered poor on contrast. Amazingly the JVC claims 15,000:1 contrast, and that's without even having a dynamic iris, which is so heavily relied on by other LCOS and all LCD home theater projectors.
Seeing this image on the screen, was simply awesome. This tiny picture doesn't begin to capture the RS1's abilities: You can click on these two images for larger versions:
But enough technical mumbo-jumbo. To paraphrase: "It's the picture, stupid". Black levels are a magnitude beyond every other projector tested, and the result is eye-popping performance unmatched (at least under $10,000) It's quite possible that the $30,000 - $50,000+ 3 chip DLP's may match or outperform the RS1, but at 5 times the price, how many of us really care.
