I have an early version of HD plasma, Viewsonic 425. The picture was never look good on HD (component inputs) for a few years until recently, when it is plugged in a Monster Power Bar 2000 MkII. The display is much improved with the conditioner. The picture can rival newer models with clearness and color correctness. In fact, I like the color of this Viewsonic more than many saturated color LCD/Plasma of my friends who have just got the LGs and Samsungs.
So I won't go without the power conditioner for the plasma.
