> I've created a dragon in my head

In a way, yes. The reason this happens is because human minds are always, always trying to equalize with their environment. So if you get used to something, your brain will basically invent things it wishes it had because it got used to what it heard.

Best way to fix that; listen to worse gear for a bit, then wow yourself all over again.

I keep a pair of 6XX specifically so I can go back to my Ananda and go, "Man, literally everything is better, damn these things sound so fuckin' good."

Keeps me sane.
