I will keep this in mind. I will show my patience and just have fun with it.
My whole idea was to get a kickass headphone for gaming and movies on TV. Can you please help me on how is the best way to connect it to the TV? One of the friends was saying, wait for the 650s to come and simply try plugging them into the TV directly. Another thought process was Dolby or Surround Sound (or some semblance of it) will only come via optical connection.
I also want to connect it to my PC. I have a Ryzen 5 5600x with ASUS ROG STRIX B-550 Gaming-F motherboard. From what I know, it has a pretty good built-in sound chip (or whatever it's called).
One friend was recommending a Schiit Modi 3+ from headphonezone since it also has optical.
All in all, I just wanna have a good time watching movies and playing games on my OLED TV. Please guide me.
I recently purchased Wi-Fi version of this B550 F gaming motherboard. On board DAC chip on this motherboard is very good. I tried it myself it can decode DSD format as well, although not claimed by the manufacturer. So if you want something to use with PC you can consider an amplifier something neutral sounding like topping A30 Pro.
Can also consider something like fiio k5 Pro or schiit amplifier.
Avoid ifi , tubes or any other warm sounding amplifier.
At the moment you don't need a DAC you just need an amplifier only.
Also buy a 3.5 mm to stereo RCA cable, to connect rear audio port from your motherboard to amplifier input.
You can also use this cable and amplifier setup with your TV if it has 3.5 mm headphone jack.
Usually optical port on TV or motherboard is used to connect a AV receiver etc.
I do own a LG TV as well and I know these LG televisions are very capable of decoding various audio and video formats so I don't think there is a need for a DAC unless you are using a receiver with dedicated multiple speakers setup.
The last device in your audio chain will be headphone only so why bother with making it a long chain from (optical to DAC then amp then headphone).
When TV can decode almost all formats it's better to use 3.5 mm port on TV to amplifier then headphone. The only format missing is dolby atmos all other formats can be decoded by television itself including dts-hd.
I hope your TV has got 3.5 mm audio jack.
I can understand you need some surround sound effects and openness for movies but no headphones can match dedicated home theatre speakers setup. Maybe something high end and expensive can get you that theatre feel.
