We currently own Samsung HLN507W, which the wife agrees we will replace before the end of the year. We are primarily looking at LCDs, but every so often the wife asks why we don't consider another DLP since we have been happy with the one we've had for almost 5 years and we could save a few bucks. So I always take a quick look to see what is up with the new DLPs.
Last year's Sammy DLPs were terrible. Maybe they were rated 1080p, but I wouldn't have traded my current Sammy DLP for any of them. My wife was shocked when she saw them. I saw some Series 6 units about a month ago and was impressed with the improvement in PQ and horizontal viewing angle over the 2007 models. Today, while on my way out of a CC store, I spotted the first Series 7 model that I've seen.
So what was my reaction, disappointment. While it definitely has a brighter and sharper picture than its predecessors, this LED DLP pales in basic video sharpness, depth of color, and viewing angle to the Series 6. No way would I replace my current Sammy with this model, it isn't as enjoyable to watch. Now I would consider a Series 6 based on PQ, since it would be equal to or better than my current Sammy; however, the comments on this thread about bowing issues certainly discourage that.
The CC store where I saw the Series 7 had a Mitsu (don't remember the model number) next to it and a Series 6 next to the Mitsu. Walking from the Series 7 to the Mitsu and then to the Series 6 was a progression of PQ and viewing angle, with the Series 6 the best and the Mitsu second. The Series 7 just has that dull soupy color look to it without any "pop" and what color sharpness it has fades badly once you move about 30 degrees off center (no I didn't use a protractor, but I'm an ME with a PE, so I have some sense of angular measurement via visual inspection). The Series 6 PQ and viewing angle were very good and, but for the cabinet and picture distortion problem, would probably be on my replacement candidate list.
BTW, I'm not one of those who thinks he sees rainbows and I don't know anyone who has ever seen a rainbow with my current Sammy. I also don't have an issue with the lamp replacement in DLPs. I replaced my first lamp at about 7000 hours because we thought it was failing. It wasn't, it was a video board problem, so I still have that lamp as a backup. The second lamp is still going strong at over 9000 hours. Total investment in lamps for almost 17,000 hours of use is about $200. No big deal.
If I thought the bowing and distortion problems would be fixed by late in the year, I'd really consider the Series 6, but I think that Samsung is suffering the unintended consequences of trying to get the slimmest and lightest DLP on the market.
