To me, they sound fantastic. I could go on about my own subjective experience, but can summarize by saying I wholeheartedly agree with those who talk about the great imaging and soundstage. Zero buyer's remorse.
In a perfect world, I'd use an equalizer (like maybe the Schiit Loki) to bring down the mid-bass a touch and bump up the mids & table a hair. But I'm used to listening to the AKG K553, which is a much different animal. Maybe I'll try...
