I'm somewhat worried about the Picture Quality of this TV not having the same "pop" as the 71 series.
When going to a Circuit City store with their enterainment section dimmed from the rest of the store & all their flat panles lined up & hanging on the walls, The 71 series just flat out destroyed everything period.
Alongside with the Sony XBR4, Mitsubishi 144 series, Panasonic PZ77U & the Z700U models, Samsung own 5884 plasma, Sharp D82U & the Toshiba Regza, all TV's were running the same feed.
When the feed would change a scene, it would go black for a few seconds & the Samsung was the only TV that was inky black black, completely fading into the bezel.
The XBR4s blacks were pretty bad being greyish & hazy, The Panasonic panles were a distant 2nd from the 71 series, Samsungs own plasma was 3rd & the Mitsubishi had the 4th best blacks.
Same when the screen turned all white during the feed. The 71 series just absolutely blew away the XBR4 & Mitsubishi in a pure clean bright white color & the Panasonic plasmas looked so dim in comparison, you would think it was broken.
I think I would go with the better pop & colors then better AMP if the 6 series really has an inferior contrast.
