From Sound & Vision: World's Best Plasma vs. World's Best LCD
Sound and Vision took took the best Plasma TV they could find (Pioneer PRO 110FD 50" Elite KURO 1080p plasma HDTV) and the best LCD TV they could find (Samsung LN-T5281F), for a one-on-one match. The outcome wasn't even close. Pioneer's KURO technology places the 110FD Elite at the top of the heap. By far. The Pioneer, which many have already rated as the best flat panel ever, was the clear cut winner. The deep blacks of the Pioneer clearly factored in the outcome. The same technology places the entire KURO line up above all others. If you're looking to upgrade, go with the best HDTV in the universe, the Pioneer KURO. (Sound and Vision Magazine, February 2008)
"...when we looked over at the Pioneer, we immediately knew we were seeing something special. The same features were so deep that it made the blacks on the LCD look gray—even though this Samsung had the best blacks we've ever seen from an LCD. On the plasma, the car appeared more etched and dimensional against the dark background, thanks to the extra low-level detail, and the letterbox bars virtually disappeared into the set's black frame."
"...I think our results here have to be viewed in the context of the tremendous feat that Pioneer has accomplished with its new Kuro sets. The three of us evaluate HDTVs for a living, and we were all blown away by how virtually perfect this 50-inch Elite set was in its execution of every torture test we threw at it. "Best TV — ever" was a phrase heard more than once that day as it began to sink in just how good the darn thing was."(Sound and Vision Magazine, February 2008)
