Actually I am happy, I WFH most of the time and instead of having a portable rig on the bus something else at my desk at work I have my real hifi and I sit between my speakers and work so its not just about the headphones 100% I enjoy them when the mood strikes and I rotate through what I have, I enjoy the differences. I really like my Audeze LCD-2C with Questyle CMA800 its a synergy thing (was my at work desk rig) , I enjoy my HD800S with my Manhattan II, I do a lot of Roon streaming and I get to listen to my turntable when I want, I mainly listen to my Custom IEM's and AK100 when I go in the office on occasion, I think the variety is refreshing, I enjoy my headphones for what they are in terms of signature if that makes sense, I could keep buying stuff forever, but I spent enough, my equipment sounds really good. Head-fi is a one hobby, for me. It was a gateway back into my love of stereo from my youth. I started with a Fiio X3 and IEMs and realized you could pretty much have hi-fi in your pocket with hi-res files. The equipment is fun, but it's about listening to the music and enjoying it.

Have you met Orpheus ? have you been to a Can Jam or other type of audio show where you can at least experience what is out there, You experience the its wonderful but I wouldn't pay that feeling (50k insane hifiman valve amp + headphone setup ...), but it gives you perspective. I have a bunch of cans, I dont think I met the end game but yes I stopped buying, I do have an HD-800S and Audeze and Dan Clark but I'm good. It's a sickness a hobby and an addiction. But there are probably worse things. I have a number of hobbies as bad. As long as you can listen to your stuff and be happy , it doesn't have artifacts that irritate you and prevent you from enjoying the music. At some point its a diminishing of the veil adding detail and different sound signatures. And synergy its often about the synergy.
