I just got back from my 1st day at CEDIA, and boy am I tired! Since I was mostly interested in learning everything I could about the RS20, perhaps here is the best place for me to give a general report:
1. RS20. I finally got to meet Jason today, right at 10 am when everything opened up, at the JVC Pro location just off the CEDIA site. (He's younger than I had thought!) Ken (?) was JVC rep displaying the unit and answering as many questions as possible. I thought it looked fantastic, very deep contrast and rich colors. Some specifics:
a) Ken said without qualification that the 800 lumen spec is at 30,000:1 CR; i.e., they are not separate measurements under different conditions. (I also asked this about the HD750 at the JVC Consumer location in the CEDIA site, and got the same reply.) I then asked that if one closed down the aperture, to reduce lumens, wouldn't one get higher CR; he said most likely, but that they were not advertising this. He said that the higher brightness was due to the re-designed light path. He also talked about the THX setting that is preset to rec 709, etc.
b) YES, it IS quiet! I climbed up on a chair so that I could get my ear within a couple of inches of the exhaust vent and could JUST barely hear it. This was in low lamp mode. In high mode, I could hear it, but it really is modest, not as much as my RS1 in its low lamp mode (and which has never been a problem for me even thought it is within 2 feet of my head). The amount of hot air coming out of the RS20 in normal (low) mode is also very modest; I could not feel heat if my hand was 8" or so from the vent. (THis is imp, since the vent would be on my wife's side if I get the RS20!)
c) The pic was very sharp, and there were no bright corners (as there are on my RS1), etc. But just how good it is, in comparison to other good pj's, is hard for me to judge without a side by side. But I do feel safe in saying that overall it is better than my RS1.
d) I also tried to measure the distances between the 'feet', and thus mounting holes; they are about 12" apart front to back, and 9.5" apart side to side. But don't drill any holes yet, this is just a semi-quantitative estimate (I used a sheet of 8.5x11 paper!)
e) Ken also said, like Jason, that the prices of the RS20 and RS10, would be BELOW those of the RS2 and RS1. (And I hope Jason can negotiate a good 'prebuy' price for us AVSer's.) I told them how strange this sounded (not that I wanted them to increase the prices), since the RS20 was an RS2 with a number of 'pluses'. He agreed and seemed to reply that he didn't think this up. It seems clear to me that the RS1/2 will be dropped as soon as supplies as exhausted and production of the 10 and 20 are up in full gear.
Now some other random thoughts about other things I saw:
2. I saw JVC's 4K demo, and it was impressive, but what really excited me was their 3D demo. This is something I could go for (assuming of course that there is source material). It was a rear proj setup, using 2 1080p projectors, one for each eye. The rep said that this is the only 3D system that provides 1080p per eye. It is far from being a 'product' at this stage, but he said that work was providing toward this. It will probably be quite pricey.
3. I was disappointed that Sony was showing much of their VW70. It was used to show a stock Sony ad, and actually looked quite dim to me, but they really didn't demo it to any extent. My guess is that it's just not quite ready.
4. I saw the Planar 8150 for the first time. I liked it but wasn't blown away. It has that classic dlp look, spectacular on bright action scenes, but not as much resolution of structure in dark scenes. But I consider it still on my 'list' of possibles. I would really like to see it side by side with the RS20.
5. Also saw the new Epson 7500UB and Mits HC7000. They both provide very nice pics, and both are priced at "< $5K". There were some questions after the Epson demo from some knowledgeable folks, though, asking about white field uniformity and pixel alinement, and the rep said that these were better, but that this was not lcd's strongest suit. The Mits 7000 was shown under very poor conditions, so it was hard to tell just how good it might be.
6. Saw the Sammy 800 (JK himself was there). I thought the pic was spectacular, esp the colors, which are of course what JK is famous for getting perfect. The throw ratio for this product, though, puts it out of consideration for me.
7. Looked at the Mits laser-powered dlp rptv's; they looked super (for rptv's). The rep said that, yes, they were working on this for front projectors, but no predictions.
8. There was no TI booth, and essentially nothing about led-dlp projectors. I asked at SIM2, Marantz, Planar, and Samsung, and no one would say anything about led-dlp. ??
9. Sim2 had no new pj's (other than the 60e), but I did look at the C3X1080p demo. Yes, it does look spectacular in bright scenes (would be great for sports!), but again I thought that things just tended to fade to 'black mush' in the darker scenes. (This is probably stated it too strongly, but you know what I mean.)
10. Similarly, Marantz had no new pj's, but I looked at the 11S2 again; it really is a beautiful pic, though probably not as bright as I would like. The rep did say that the newer units now produce an ANSI CR of 1000:1, now the world record (and same for the 15S1). He said this was due to a new lens coating that had been developed.
OK, enough rambling! I will also spend tomorrow morning there, and since I've covered all my 'essentials', if anybody has anything they would specifically like me to try to see, post something by 9 am tomorrow.
