I just got my 65733 delivered yesterday morning. Great set! I must say though, that as expected, the settings out of the box were EXTREMELY bright. They had the contrast jacked all the way up, the main picture 'mode' set to 'Brilliant', they lamp turned to the bright setting. Man, I thought is was going to burn the retinas right out of my eyes! Not to mention, with it tuned that brightly, the SSE was VERY apparent in almost all scenes.
However, a little tuning with DVE (what little I can do with my limited knowledge) with gray scale, tint, contrast, color, etc, and WOW! what a great TV! It's really quite stunning, for HD OTA, HD via Sattelite and of course HD DVD! The colors are very natural, the resolution is fantastic. Once tuned, I could not even detect SSE.
For those interested in the noise, I did hear the 'whine' of the colorwheel, but it was really nothing distracting. In fact, it was a bit quieter than my previous 50" DLP TV. With the volume on (any sound), I couldn't hear it any longer. No other noises that I could hear.
For those interested in ideal stand height - with my couch, which sits just a little lower than most couches (and of course seating heights differ from couch to couch), I have the TV at just about the perfect height with a 20" high stand.
So far, my initial impressions are that I am very pleased, and that it's very important to do some adjustments to the set before you can get a good idea of what it's capable of.
