Hi Paulie, I can give you a hand. First: What would be the distance between you and the tv? Approximately.
Second: Are you really interested in picture quality AND sound? Because it's almost impossible to get both of them in a TV. There are so extremely good examples, but they're expensive and, honestly, you can have better sound with a sound bar or a dedicated HT, or even cheaper, with a good pair of headphones.
Third: How much do you want to spend on the TV? It's the only thing that you're planning to buy, at least for now? Or do you have plans to keep upgrading the setup in the future?
My only recommendation for now is STOP whatever you're doing and DO NOT BUY a Samsung. Those TVs are GREAT popping up the colours and contrast, but what you really want is to have the ability to calibrate the TV to get the most accurate representation of everything out of it.
My experience with Samsung has led me to believe that almost any fuc·$&· TV they produce, even with their own factory settings, is too damn over saturated. What's commonly known as Colour BLIND. Even after making some serious adjustements the majority of them couldn't reproduce the spectre of colours that they supposed to be reproducing, which is not good, like, at all.
I just did a like research on the website you shared, and there is no much variety. Do you have any other website?
You may think, but this guy is all about Sony, well, yeah, I trust the brand, never let me down, but there are other choices as well. If you want, answer me and I'll give a hand
