My KDL-70R550A was delivered from Amazon today. The Air Freight Company showed up within the stated window, unboxed, attached the pedestal and placed it on the stand. They patiently waited while I connected the HDMI, LAN, and Antenna cables so I could check out the set.
I am coming from a Toshiba Regza full array local dimming set with great blacks. The R550 holds it's own in that regard. I have noticed no flashlighting, edge light bleed, or banding. DSE is not noticeable nor have I noticed any lack of uniformity. I have been using the out of the box custom setting with ECO sensor disabled. I ran a quick check using the AVS calibration disk and found black levels, contrast, color, and tint to be spot on. To my eye the warm color temperature looks fairly close to rec709, but we all know the eye can be deceiving. I will not know for sure until I break out the meters and check the greyscale.
I think the R550 provides the best overall picture quality as compared to any of the Sharp or Vizio 70" models I have seen this year. I have yet to see the "M" series in the 70" size.
3D has yet to be checked and I will get to it as I can. So far I have a very nice first impression of the Sony in our home...
The R550 is a May build.
Awesome, congrats.....enjoy the 70 inch Sony
