I couldn't imagine a more extreme difference in sound. Audience will bring out the top end detail and air, while the bottom end and lower midrange will tighten up considerably. Switching from Cardas to Audience is a complete tonal shift. I made the switch at one point, and while initially blown away with the difference found Audience painful on poor recordings.
Cardas is much more forgiving up top, while adds warmth (and weight) lower down.
Really depends on your preferences and associated equipment.
