I hear what you are saying about inbuilt speakers on tvs
@kenshingintoki but unfortunately not everyone can have a full surround set up, and it's not always due to money.
I used to and i loved it.. had atmos ceiling speakers the whole shebang but due to circumstances in my house I just couldn't use it due to the roaring noise it made so I have to make do with tv speakers unfortunately.
At this point in time the tv top of my list is a gx77, 1k more than your cx77. i'm will to pay 1k just to get my tv closer to the wall a couple of inches.
I also had a AF9 oled back in the day and believe me the acoustic sound p1ssed over any other tv I had for sound.
Not wanting an argument or whatever just get a little ticked off when I always read people say stuff like "any serious av user it not going to buy a 5k tv then use tv speakers are they" etc
Some people just don't have the option due to whatever circumstances
