My dad's set was pretty awesome. He hadn't messed with any of the calibration settings and the little bit I did, I was able to get the picture looking really nice (at least I thought so).
Discovery HD Theater was breathtaking (we watched Sunrise Earth for a bit and kind of got entranced.
I can't wait to go home for a night or two and bring home the A2 to see HD DVD on that set. Buy it Mag...it's a great purchase.
