Since this thread has wandered to comparing the Sharp 90 to the Sony 70' Qualia 006, i thought I'd add this post.
I've been following this thread because I have owned a Qualia 006 since 2006, with the optical block replaced about a year ago and though my second block hasn't failed yet, I know it eventually will. It took almost 5 years for the green blob to appear via the first block, so I hope I have another couple years with my Qualia. I've been following the Sharp 70 Elite thread, then the Sharp 80 thread and now this Sharp 90 thread so I'll be ready when my Qualia finally fails. I've only seen the 3 Sharp sets uncalibrated in a Magnolia. To my eyes in the store setting, The Elite 70 definitely has darker blacks than my Qualia 006. Both the Sharp 80 and Sharp 90 are impressively BIG and since price is not my objective, if I had to give up the Qualia 006 today, It would be between the Elite 70 or Sharp 90. If Sharp would make an Elite 90 it would be a "no brainer" for me, but with Sharp's financial issues, I doubt that will happen.
While I haven't been able to compare the 3 Sharp sets side-by-side to my Qualia for obvious physical reasons, I have of course been able to drive about 10 minutes back-and-forth in front of them all in the same day.. To me there is something about my Qualia 006 that generates a more pleasingly "analog" picture. It may be its professional calibration and additional processing by the Anthem D2 Pre/Pro it is connected through. The Sharp 80 + 90 pictures seem more "digital" to me and the Elite 70 about perfect, though less dramatic only due to size. < totally unscientific and based wholly on store setups.
I have VERY much appreciated the comparison statements by the previous Qualia owners. < Thanks much!
