Hi... This is an excellent set...I would say there is no differance between Quality between this and the 9986. Would like to make an addition to the settings by Jimsan (excellent by the way mate!) Picture settings...by Jimsan http://www.avforums.com/forums/showpost.php?p=1419573&postcount=2 For those who are having trouble with audio distorsion...I also noticed the audio was on some scenes distored...After a couple of tweaks it's perfect. Goto sound option...then equalizer... The 120hz needs to be turned down by 3. The 500hz needs to be turned down by 2. I find these settings optimal. Try these out and let me know what you think.
