Actually my time was even better than I had expected. After a short trip and traveling trough some of Switzerland's most picturesque regions together with a friend of mine we could see a VW760, VW870 and a N9X. Side by side in a completely optimized black room. Screen material was about gain 1.0 and its width was only 2.5 meter.
There were not too many people there. I think hardly more than 10 at the same time. But as a Swiss I'd say: quality beats quantity. Ekki Schmitt from C4H was also there. So I knew the projecotrs would be set up as good as possible. Every aspect that makes up a great picture was analyzed with appropriate test and demo material. Everything was tried to squeeze the best out of these beamers. All settings were transparent. Any question was answered and any suggestion for a setting followed. Beeing a rather experienced user I appreciated that tremendously.
Now I guess most people - particularly in the VW995 thread - would probably like to know whether the VW995 is worth the higher price compared to the 760 and also NX9. I think everyone has to answer that question individually based on his setup at home. What I could say as a general and summarizing remark: we all agreed yesterday that in a blind test most people including us would most likely to have a very difficult time to tell which projector was actually running. In most cases I could only tell it was the 870 because it was brighter than the other 2. With HDR I could tell it was the NX9 as it projected slightly better blacks in low ADL scenes than the 2 Sony. But unfortunatelly the NX9 was also the darkest in mixed scenes. Sometimes I wished also to see better differentiation close to black.
Could you tell the better lense ? Yes, but only in still pictures but not during a running movie. Interestingly: we compared a Windows folder with several file names. Tiny black fonts on white background. Text was more distinct and better to read on both of the Sony. Even at the edge. However if you did a test with white writings on dark background the NX9 was better.
So much to the better lense ...
Is the Digital Focus Optimizer any good ?
No from what i could see. It is rather adding artifacts than improving sharpness. The lense 870 does not need that IMO. So rather a marketing gag. Which reminds me directly of 8-shift. I could not see any benefit when engaged with the NX9.
Generally and from a personal point of view I would have liked the brightness level for HDR material to be higher than what I saw yesterday. This applies to all 3 of them. The 760 and 870 were run at Laser 100 for HDR and the JVC at high lamp mode. Personaly I use a screen of gain 1.3 to 1.4 (about). An Oppo was used and having a Panasonic ub9004 at home and having seen MadVR feeding a VW760 I think there would some potential left. But it was the same for all projectors yesterday. The Sony have the advantage of the Contrast Enhancer that helps with brightness. Ekki is using that with excellent results for HDR. The filter of the JVC costs about 21% brightness - too much for me. I clearly prefer the Sony approach without filter but less DCI-P3 coverage. Therefore with the JVC I would disable the filter.
We had a look at low ADL scenes. For example The Revenant end of chapter 4. Here you could tell that contrast was best with the NX9 despite diffentiation still could be better. The 870 was not far behind - particularly when we disabled the filter with the NX9. Of course this leads directly to the question of native contrast numbers. Ekki announced some measurements to be published by him pretty soon. I don't kow what he has measured but I would guess that the native contrast of the JVc will be around 1:30 K without any iris tricks. Some data that were already published by some reviewres look at least reasonable to me. Native contrast of 870 / 760 will likely be identical . Only dynamic contrast will be different due to the iris. For ANSI contrast figues I am particularly curious.
In Sitzerland the VW570 costs 8.3 K CHF, the VW760 costs CHF 15 K, The NX9 is 20K and the 870 is 26 K.
I exspect the VW570 to deliver about the same picture as the 760. So the laser is about 7 K CHF. Based on that the pricing here seems reasonable to me at least. Personaly I would never go back to a lamp based projector. One of the reason is the loudness. The NX9 on high lamp was clearly too loud for me and my setup. It is not better than the X7000 that I had. This was a bit disappointing considering the much bigger sitze. Of course still not so bad like the Z1 but inaccetable for me on high lamp mode. There is also some noise coming from the iris of the NX9 but this might be a preseries related issue.
So the 870 confirmed my first impression of a well balanced projector with hardly any major deficiences. It squizzess out some potential that the 760 has left. From a personal point of view as a VW760 owner the practical value of the improvements are rather neglectable. My only major point for potential improvement is that you can not set the iris to a user definded value. This would be a highly welcome feature for SDR material from my point of view. Maybe next generation.
