"The Ruby got to go "
--------------------------------------------------------------------------------
Just wanted to add my two cents on this projector. As you can tell from the mini-heading, I own a Ruby. And from my signature, you see that we are serious about picture quality as we work with HD studios on proofing their HD DVDs. So having the best display is important to me. Until now, the Ruby did the job. But no more.
First a bit of background and special thanks to OP for creating this post. I was searching everywhere for JVC booth with no luck. Nothing in the directory, etc. Having heard about the stellar reputation of this projector from Elliot at PJ HiFi in UK, I was anxious to see it in person. So armed with the location, I showed up at the suite in the hotel.
After introducing myself, I was treated to amazing reception by JVC folks who spent nearly two hours with me, showing me both the consumer and professional versions of the projector and the rest of their technologies. I have to say, until now, I was caught between the Sony Ruby and Marantz 1080p DLP projector we use in the HD DVD mobile theater. The former does not resolve full 1080p and its lens is rather low performance with a ton of lateral chromatic aberrations (color bleeding), and strobe/rainbow effect of the Marantz which otherwise, fully resolves 1080p. And while I like the extra contrast that that the dynamic iris provides in the Sony Ruby, I did not like its sudden effect on light to dark shots, or the fact that it takes down the brilliance of bright objects on dark backgrounds. Still, it is a nice projector and I preferred it to the Marantz due to lack of rainbows.
Then I got to see RS-1 and it was best of both worlds. Great contrast and sharpness like the Marantz, but without the rainbows. No dynamic iris and great contrast ratio. I also like the manual focus as it is impossible to get precise focus on the Ruby with the remote. And of course, it is half the price of Ruby and a quarter of Marantz.
The lens is also of much higher quality than the one on Ruby. On white text, the Ruby would bleed more than one pixel worth of green/red. On RS-1, it would bleed one blue pixel. I wish it was more perfect than this but it is still a huge step up from the Ruby.
The machine is quiet and I like the fact that it blows the air to the front sides. I have to keep the Ruby away from the back wall where I really want to mount it and it cooks anything behind it.
RS-1 has a glossy black finish. It is less high tech looking than the Ruby but black is better in my book for something I am going to hang off the ceiling.
Uniformity was very good which is nice as some people complain bitterly about it on some Pearl units.
It is also very nice to have lens shift in both directions.
Response time was very good and I did not see any smearing. And it was great to see no noise in dark areas as is common in DLP designs.
So off goes the Ruby as soon as the RS-1 arrives.
Much thanks to JVC folks for being so darn to earth and accommodating. This is key to winning the hearts and minds of the folks who hang out around here .
