Dive right in.
You can start a new topic on the Headphone Mania forum:
https://www.audiocircle.com/index.php?board=147.0It will help significantly if you can describe your current setup, your listening preferences (both genre and the things you like in terms of sound (e.g., you need heavy bass, you want a broad, expansive soundstage), and what you are considering or have as goals (e.g, I want solid state that connects to my computer or I want a setup that can serve double duty in my main 2-channel system).
And clearly indicate how much you might spend. It doesn't have to be exact, but it's really hard to give useful feedback if there is no ballpark on the cost. Keeping it less than $1000 is very different than "I could spend $2,000 to $3,000 if I find what I'm looking for."
It can be a frustration if someone starts a "what do you recommend" thread and piecemeal replies with critical information after the discussion gets going.
It's understood that your understanding and interests might evolve as the discussion goes, of course.
Have fun!
