Well, good for you.
As an engineer, objectivist foremost, and as someone that believes and knows that there is more than meets the eye in the human psychology (which actually meets the eye on a global scale looking at the practices of humans in case of a pandemic dealing with a difficult to grasp situation), I rather keep my objectivity and trust the science.
That said, I also have the T+A HA200, which costs not too far off from DAVE, running a 3090 and 24 core system infront of me to experiement with upsampling etc., plus I am fortunate enough that my objectivity and analytic thinking has earned me an OK life that I can afford any headphone gear I want. But I would rather keep my feet on the analytical grounds, as there is a lot of BS in this industry. People claim they hear things the measurment devices cannot, but it is often otherwise is true that measurement devices are much more precise and sensitive than humans. Whether someone likes the outcome or not, that is another subject.
Enjoy your gear.
It is in the end what matters.
