Had a demo today. I'm still wavering on which pj to buy for my first hc experience. On price and reviews the Z1 is looking best but now there is the Z2 to consider! To help me choose, I had a demo of both today. As you will see, I'm no expert and I don't know whether the following will add anything to other posts on the forum but here are my views: The demo room was good and dark with the projectors set up 14' from the (110") screen. Seating was about 12' from the screen (pj on a stand just behind the seating). This is pretty close to my room size. I think the DVD player was a Denon and it was connected via component. Both pjs were out of the box (default settings). First up the Z1. At this seating position I think I was too close to the screen for this projector. Screendoor definately apparent. Not terrible but too much for me - slightly defocussing certainly helped. Colours were good, if a little warm. Contrast was good. Brightness was good too even on low bulb setting. All in all a very watchable picture. Fan noise from just behind my head was a little louder than I would have liked. Moving to stand behind the pj improved things greatly. Screendoor disappeared. I did notice though that there was quite a lot of light spill out of the back of the projector. If it was on a low table in front of the seating position I wonder whether this would be annoying. Moving on to the Z2. Immediately noticed an improvement to contrast and brightness. A really sumptious, punchy engaging picture. No screendoor visible but disappointingly, very noticeable fine vertical lines a bit like thin pencil lines (is this banding?). Where this was really noticeable was in moving areas of fine detail - they sort of shimmered and looked out of focus (as the detail moved across the lines?). I didn't like this at all. The fan was virtually silent on low bulb mode but was too noisy on high. As an experiment I moved the projector to just in front of the seating. The shimmering was much less evident and the picture looked great (about 90" diagonal) from the seating position. No light spill from the back of the projector. So which will I choose? I think probably the Z2 but I'm a bit worried about the lines I could see. I think I'll have to go back for a second demo armed this time with any recommendations anyone can give me for adjustments from the defaults that may improve things (I had a quick fiddle with things but seemed to cause as many problems as I improved).
