Had my first encounter y-day. Few subjective musings I noticed during my 25 minutes, so basically 2 cents from me:
1. Lens quality
Looked at the built in test pattern, so nothing as good as what Arrow is doing, but still I have to say really good uniform sharpness compared to my 520ES. I spent a minute trying to examine the lens, looking at the projector from 20 cm distance and it looks abolutely the same on the 760ES as on my 520ES. The entire screen was sharp and in focus, only slightly less sharp in the extreme corners. I must go with the guess that they are saving the best lenses for the 760ES, a la X9 JVC series. Nothing to complain about here if this is representative of all the other specimens!
2. HDR Picture
Only watched scenes from Revenant, which to be honest is a little bit drab. Color wise, when there was blood in the river it stood out to me as the coloration was on an elevated level compared to previous SXRD HDR offerings. Wish I had had the time with more titles that would illustrate the color space more. Light wise, it was on Max Laser level and I had the feeling, that has been reported previously, that subjectively it unfortunately did not produce leaps and bounds above the 520ES in total light output. Maybe I need to point out that it is better, but filling a 130" scope screen like the one in the shop with 4k UHD HDR disc material is not an easy task. So pick your poison of a bit of Dynamic Range Conversion on a Panasonic player or some custom gamma curves if you feel inclined to improve on Sony's built in tone mapping unless you have the money to move up to a 5000ES!
3. Laser performance and Sound
As stated, we ran it in 100 Laser. I was a bit put down by reading 52 dB in this thread, but in all honesty it felt almost whisper quiet! Full force, and still hardly a breeze. Measurements is absolute, but I implore you to go and check it out in real life, because I could not hear it over the movie sound! Muted, you heard it but it did not bother me in any way. Subjectivly for me on a lower level than the Z1 in max laser which I saw in the same room. No doubt. Subjectively lower than my 520ES at home on high lamp. Did not try on 80 Laser, but if that is much lower then that's virtually imperceptible. Projector had been on for 7h uninterupted and it was hardly warm to the touch! Maybe 35C at it's warmest point, on top mid at the back. The laser drive has been constructed well indeed!
I long for one in my own room! Took a picture to console me while waiting!
