There’s an Edition XX thread that would be a good home for detailed impressions, but since you started the convo here would be nice to see a link to over there whenever you post your thoughts.
Just to expand on earlier comments about “endgame,” this hobby presents nearly endless ways to explore audio as deeply and in as many different ways as your wallet and curiosity will take you. Like different transducer types, SS vs tube amps, IEMs and portable gear, different tunings (clinical or “fun”), etc. There is no one common, objective definition for “perfect,” and there are many different branches leading to their own subjectively sublime limits.
Variety is the spice of life. I think of headphones kinda like a high-end knife block–you could get a fine chef’s knife and use it for everything, and you wouldn’t be wrong or lacking in capability. Or you could expand to bread knives, vegetable knives, utility knives, pocket knives, razor blades, swords, and hatchets and have the absolute perfect tool to cut anything, lol.
Whatever you do, don’t feel obligated or afraid to blow money on this hobby as long as it brings you joy and you keep it in balance with your other obligations and priorities in life. Welcome to the rabbit hole. 
[EDIT: took too long on my silly metaphor and beat to the punch on the pertinent info, lol]
