How did you know when you reached your endgame? I'm wondering how much happier I would be with another high end pair of headphones--or if this is just upgraditis. My favorite headphones (so far) are the Mr. Speakers Alpha Primes (which I settled on after passing on the HD800 and LCD2). The way I have them tuned with "doggie treats," the sound just gives me the happy warm fuzzies every time I put them on. They've effectively ruined all the mid-fi cans I used to love. Is that as much as I should ask for, from a pair of headphones? I feel grateful to be as lucky as I am, for sure. I don't doubt I would be happy forever with what I have now, but the same might well have been true when I was listening to an M50x out of my phone, when that was the best I'd experienced. It's hard--if not impossible--to imagine what better would even be like, if you haven't heard it. I can't even tell you what improvements I want, because I don't have a way to know what improvements are possible. My setup: I run an ODAC -> a Kenwood 45 wpc speaker amp running a TRRS plug off the speaker posts, so I have all the power that any headphone could theoretically need. I also have a Stax SRM-727a with a Lambda Pro, so improving my electrostatic setup is on the table too. I'm not considering upgrading my other (non-Stax) source gear at this time. Pretend that money isn't much of a factor: I can and will save up for a Focal Utopia in 6-12 months, if being patient for that long looks like it'll be worth it in the end. Planning to save for longer than that isn't practical for me.
