I received my 6500 UB yesterday (12/22 about 4:45 pm) and all I can say is "WOW!"
Now keep in mind this is my 1st projector ever, but I am truly blown away. Ok, so I'd probably be blown away no matter which one I bought, 120 inches is 120 inches. Beat that 50" DLP TV! Anyway, I have only watched one full movie, and several clips of others, but the picture looks great. I did a quick calibration (not much time to put into it yet), and it looks wonderful.
A few notes:
1) The convergence of the LCD panels is definitely off. I shot a test image onto the screen and I am off 2 pixels, as I can see a magenta line on one side and a green line on the other. This seems to be STANDARD with Epson, so I'm not even gonna bother exchanging, as I would probably end up with one with dead pixels and even worse convergence. Please note that I see the convergence problem only when I stand at the screen and analyze it, not from seating distance.
2) Frame interpolation: cool in a 60's dropping acid kinda way... but to me it's really kinda unwatchable. I had a few friends over to watch a movie, and we played around with the frame interpolation feature. Very weird! Very smooth motion (no judder, blurring), but very unnatural. I can't see myself using it. My friends agreed it looks strange, but they thought it was really cool and wanted to leave it on... My house, my projector = no thanks on the frame interpolation feature.
3) Black levels: I am not a good reference for a comparison, because I've never had another projector. I would have to say the black levels are excellent. They look great to me... however, I can tell you the black velvet frame is ABSOLUTELY blacker than the horizontal bars on 2.35 movies. But unless you are trying to be critical, you won't even notice them.
4) Mounting: easy to mount, but I bought a Sanus Universal mount, and I had to use some extra pieces because the mounting holes on the projector are so far apart. Make sure your mount has long arms to reach each mounting hole.
5) Colors - Again, I barely calibrated it. I used the THX calibrator from the Monsters, Inc setup menu. I am not a calibration expert, but I would have to say the skin tones, and colors all look natural, yet rich. I love saturated images... not overly saturated to the point of everyone looking sunburned, but enough so that the image looks full, not pale/dim/washed out. This projector doesn't disappoint.
6) Noise: If you are really listening for it, you will hear the fan blowing quietly. During the movie (and even during quiet scenes), you will not hear it. I am sitting only about 2-3 feet behind and about 4-5 feet below it, and I never hear it. Some very picky people might say they can, but again, that's only for those extremely critical people.
I have read dozens of projector reviews from projector.com, projectorcentral.com, projectorreviews.com, bigpicturebigsound.com, and the list goes on... that being said; I am no expert, but consider myself someone who at least knows what to look for in a projector. I still say "this thing is awesome!" I am a very critical person, and I always look for the smallest details on everything I buy (and the women I date, hence me still being single). Only the most critical person will find any problems with the 6500UB.
Well, that's about it for my quick review. If you have any questions about the projector, please feel free to ask. I don't have to work 12/24 so I'll be watching a few movies, hopefully... I should be available to answer questions if you got 'em!
