Below are thumbnail images of the full DTS screen (from my DTS Blu-Ray demo disk). Click on them for closeups of about 20% of the screen area. For your consideration, click on the second thumbnail for similar image from the Sony Pearl, and the third, for the JVC RS1. You can definitely see that the Sharp, is, - well, sharper. Remember you are looking at a closeup of about 15% to 20% of the area of the whole screen. The question is can you see the difference under normal viewing distances. The answer is - yes, in a side by side, you could, but it is unlikely that you could tell them apart in terms of sharpness, if you viewed one, and then another 10 minutes later. Still, while every last ounce of sharpnesss is a good thing, it is most unlikely that the difference in sharpness will be a critical factor in most decisions - even for folks who like to sit as close as I do.
