Short answer: the AsciLab C6B, clearly. The Zu Audio Method measures high sensitivity, about 90-90.7dB average through the 300Hz-3kHz vocal range, but it has a severe suckout in the 1.5-3kHz range, down as much as 19dB below the mean at its worst, removing attack and clarity from brass and woodwinds. The C6B gives up some bass below 50Hz in-room but keeps a far more even response, and it costs $1,145 against $700.
Buy the AsciLab C6B. It is rated higher for sound quality, and the $445 you would save on the Zu Audio Method does not close the gap.
