I took the plunge and purchased a 55 inch A9F in January. I couldn't be happier with my purchase! I have watched a variety of content during the last 3 months and continue to experience exhilaration daily. I kinda wish that I had purchased a 65 incher, but I compensate by sitting 6 feet from the screen. I may purchase a premium sound bar if a great deal comes my way, or perhaps on Black Friday. I started out with the Sony HT-ST5000 hooked to my tv, but I just moved it to the 940E to impress the wife. Now I have an excuse to buy another soundbar for my tv!
Unfortunately I fear that addiction has emerged, as I have also purchased yet another TV and other components as shown in my signature. I'm a newby and I'm still learning something every day. I've been pouring over the forum posts and have gleaned a lot of helpful info. I do a lot of experimenting as well.
The wife isn't as exhilarated as I am, so I preemptively granted concessions in the area of home improvements such as painting the house, new carpet, etc. Still, it was a good deal for me. I gained an office/mancave as well as top notch TV's and peripherals. I can't complain.
I told my wife that I intend to watch more movies with her on our new tv's. It will be so romantic... wink, wink.
I'm not a cinephile, so I didn't do any targeted testing to find flaws. As far as I can see there are no obvious flaws, and my A9F seems to have a great screen. I'm taking Plasma's TV's sage advice, and I'm just enjoying my new top notch TV's!
