I have a few headphones and IEMs. I like all of them but I favor the HD 25-1 II which I generally drive with an IBasso D10.
What would be a significant upgrade from the HD 25-1 II with a similar but more refined/improved sound. Budget would be under $400, the more under the better....I get off on value.
I typically listen to Dire Straits, Pink Floyd, Bob Seger, Supertramp and similar sitting down in a quiet room room at home.
All recommendations would be appreciated.
