Question: 52XBR4 compared to 52W3000 Able to get XBR4 for 3100, or 600 more than W3000 and wondering what others think. Anyone compare them side by side? Besides the 120Hz refresh rate, other differences?Thanks for any input.
Document: Everything works flawlessly and looks better than I could have ever imagined.Another big change I've made is the 120hz motion flow. Originally, I didn't run this feature while watching television/live action movies because the faster refresh rate made the video look too much like it was shot with a home video camera. But after having this tv for a while and viewing more and more BD content (thank you netflix) I have grown quite accustomed to watching everything with the 120hz feature on and think it looks great.
I researched flat screens for almost a month to the point where I needed to stop as I was starting to over-analyze. I knew that I wanted to go LCD as our tv sits by a rather large picture window and didn't want glare from the window to be an issue. I trimmed the field down to 52 inch 71 series Samsung(120hz), the Sony 52 inch XBR4(120hz) and the Sony KDL-52W3000. I went to one of the big box stores to compare visually.
It is unfortunate, but I did not get the chance to compare them side-by-side but I can tell you they are very, very close in terms of picture quality.In reviewing prices, the Sony XBR4 was always at least $400 more at any given time than the Samsung. When deciding to spend a sizable amount of money on a TV, especially when the picture quality was so close, I felt that the extra cash was probably not worth it.
As many others in this threads, I researched many TV sets before making my purchase decision. This Sony Bravia XBR KDL-52XBR4 set is one of the best among Sony's TV product's line. There's also the KDL-52XBR5, which is more expensive, but the  (cosmetic) differences, in my opinion, do not justify the added expense.The image, the tonality of the colors and the sound are just great. I think this Bravia XBR set is better than the latest of the Samsungs.
It came down to this....if I was going to drop that kind of money on a new tv shouldn't I just pick the 120hz technology since that is the direction the newer versions are going to? If I didn't get the 120hz set(XBR4)would I regret it down the road. My decision was made and I welcomed my new Sony KDL-52XBR4 into our home. Boy was I glad I decided on this set. Picture is fantastic.
I purchased this unit at Circuit City on 2/2/08 for $2999! Picture quality is nothing short of phenomenal. The 120Hz refresh rate adds a smoothness to sports and action sequences lacking in lesser sets (the industry standard, so to speak, is still 60Hz).
A 120Hz refresh rate, basically, in a tiny, tiny nutshell is this-most sets refresh the image on the screen every 1/60 of a second. A set with 120Hz refresh rate obviously does that fast, twise as fast, interpolating a frame, along with the original one, in the time it takes a 60Hz set to display a single frame. Along with "Motion Enhancer" turned on, it creates a much smoother picture, depending on the signal-SD or HD.
They were side by side and although the Pioneer's picture was amazing, the Sony left me speechless. The picture was so vivid, bright and sharp. I didn't buy the TV that day but instead went to another store and compared the same TV to others. It was mounted on the wall along with 8 other Plasma's and LCD's (Samsung, Toshiba, and Pioneer). It was by far the best TV up there but was almost the most expensive.
We have had our new Sony Bravia for about 3 weeks and love it. It has many ways to adjust the picture so that it's the best. The screen is good at not reflectng much light, but there is some minor reflection opposite a big window. The bright screen counteracts this well. We bought Monster's best HDMI cable to be sure to handle the bandwidth needed for the 120mhz refresh rate and the 1080p resolution. We'd definitely recommend this HDTV to others.
It was very expense then. Two years ago, I gave it to my friend and it is still in good conditions - only has minor repair once.You have to compare them side-by-side to really appreciate the difference. I did the same at local stores. XBR4 still is the best - I do not need the extra features on the XBR5. You have to watch Discovery HD and Blu-ray DVD to really enjoy the picture.
Answer: If you watch a lot of SD tv you will probably want to spend the extra $600 on the XRB4 since it will up convert the signal to 1080p.  I have the W3000 and my friend has the XRB4 and every time I watch SD tv on his I realize how bad mine looks on SD.  However if you plan to go mostly HD I would save the $600.  HD wise I can't tell the difference between W3000 and XRB4
