Nope, I don't spend much time worrying about the audio stuff either. The largest difference of course being that I can't build my own TV. But most would dismiss a lot of the gear in my sig from a technical standpoint. Oh nos, my DAC uses opamps and my transport uses some cheap drawer thingy! My amp has a highish output impedance, NOT THAT!!?!?! And my primary dynamic headphones cost $200. I'm clearly missing out on just about everything when you look at it like that. The stat rig, well, the amount of wheeling and dealing it took to put that list together is not insignificant. And it's not exactly set in stone yet.
That's fine, but not everyone is to the same degree. You make it sound like the Vizio is throwing money away, I'm not sure it's quite to that level of inadequate.
