On the down side, the Line Doubler produces a video noise that is quite visible. This seems to have increased over time, in amount and visibility. Lastly, the convergence is just satisfactory. It never has been. However, I still like the set, and believe that I may have gotten one that is not an good example of the product-line output.
Every product has a lemon or two come out once in a while.
Pioneer is attempting to address the Line Doubler issue, and though we are on the 5th visit, they are working on it responsively.
