Short answer: the AsciLab C6B on price, the March Audio Sointuva AWG on driver quality. The Sointuva’s Purifi drivers deliver exceptionally low midrange distortion, but its correct listening axis sits about 7° above the tweeter line and it costs $4,150 against $1,145 for the C6B. The C6B’s own caveat is that bass rolls off around 50Hz in-room, so a subwoofer is needed below that.
Buy the AsciLab C6B. Both are rated the same for sound quality, and it costs $3,005 less than the March Audio Sointuva AWG.
