I am very impressed with my new Sony KDL60-550A TV.
I has much better sound than all of the others, plus both analog and optical outputs for hooking up stereo or 5.1 audio systems.
It also has outstanding picture quality; top-rated by Consumer Reports. I paid $1299.
They are pretty much sold out now though, although Crutchfield still has some, and Costco has the 520 model, which is the same except it does not have 3D.
Production has gone over to the 2014 models now, and they are coming out soon. I would wait until May for a better selection and new models
Vizio is the cheapest, but there are several reasons I didn't like them, including reported trouble with audio and video being out of sync.
