I just got off that thread it is funny that the Legacy's were also discussed.
The Legacy is a bargain for the price and the sheer amount of great things that the speakers do. The Legacy is voiced on the warm smooth side, big sound stage, fantastic warm rhythmic bass, very good resolution.
The Paradigm 3F, more image precision, scary holographic, greater treble precision and speed, deep tighter drier bass.
It is a tough choice, the Paradigms sound absolutely amazing on great recordings, the Leagacy's are more forgiving of bad ones.
