I’ve owned both 2015 and 2016 versions of the Lcd-2f. I liked the 2015 version for its creamier sound better but both were very good. Having said that, I had no doubt at the time that they were not at the same level as my lcd-3f ,lcd-X or lcd-4, but I still liked them. It’s different with the 2C to me. They’re more on the same playing field of the others as far as tonality goes and for sheer musical enjoyment. It’s not a honeymoon period thing. I’ve been listening for a long time and that’s one thing I make sure is not the reason why I like a new member of my headphone collection.
