Ok guys, I got the black level comparison done. These screenshots aren't beautiful, but they illustrate what I saw during testing.
I have to say I was a little surprised. The X10 definitely has a lower black level than the HD1000. As you can see in the images below, even when the X10 is much brighter (100 iris), the black levels are about the same. What I actually observed was that the X10 was still slightly better in this case (not really illustrated in image).
Then with the iris all the way down to 27 to equalize brightness, of course the X10 is much better. I will say that 27 may have been slightly too low after looking at both of them a little more, but in any case the X10 is much much lower anyway, even at a setting of 45 which is definitely as bright or brighter than the HD1000.
I'm sure the HD1000 was closer in brightness to the X10 with a new lamp, but mine has about 800 hours on it and it shows.
Here's the setup and pics:
- X10 is on the left, HD1000 is on the right
- Both projectors throwing approximately 60" images side by side on my 130" screen.
- Both projectors on low lamp
- Brilliant color off on both
- Best image modes on both (6500k on X10, cinema on HD1000)
- Brightness/contrast adjusted correctly

100 iris again, with PowerDVD splash screen to show brightness:
27 iris this time to equalize brightness:
