LCD-3F mids are sweet, more present and detailed, just that they don't have a treble roll off compared to the clasic. Imaging is a lot better, soundstage is more homogenous. They have more attack. In my case I like bass a lot, but if that means no air, then it's a problem for me. The LCD-3F has better tonality, instrumental and orchestra is much better than it was before, violins are much more convincing, they were too thick pre-fazor. The mids did have a wow factor for me.
