Well, not sure what you mean by (C) or (F), but it was the first time listening to the LCD-3 that they actually started to impress me. As I recall (this was last October) they had better bass impact and separation, and seemed to me to have more energy...if that makes sense. Still did not beat my HD800-s on the ragnarok but the gap was closed slightly, The LCD might have had more bass ?presence? but not better overall SQ.
Okay looked up the C or F thing, not sure which one they were but it was last October at CanJam if that helps. When did the "F" version come out? Like I said not a fan of Audeze in general so have not been keeping up with their latest.
