New Interest in High-End Audio for Gaming

For right now I want a closed back because of its isolation factor, I don’t want the noise of others to interfere and vice versa.
As for what I’m looking to power, ideally I want a dac/amp setup that can power anything so that when I start getting more headphones I’m not worried about whether or not I have the equipment to realize their potential.
Also I’d prefer a mic input, I figured if the dac/amp have an optical port I could just use that between my tv. That’s how I’m still able to use my current headset by plugging it’s receiver to the tv and powering it from the PS5. So I still have chat function, and then I have to use an adapter for the Xbox controller anyways.

From the videos I’ve been watching and what I’ve been able to find I’m mostly interested in the DT 770, the Sennheiser 820 and the Celestee which I’ve understood as a good middle ground between the Elegia and Stellia

I’m definitely gonna go through that^ and see what more information I can gather then when I have a setup in mind I could ask any questions I may have.
