I've not heard the Confidence range, but the old Contour S1.4 needed something with grunt to make work at their best. Pretty much the same with the affordable Audience rangeYes I would say so. Top quality amps for the Confidence series as well. I don't think they are forgiving as they used to be and would be looking at Audionet or Restek mono's for the open window that the Confidence are capable of.
