I agree with their reasoning. To me biwiring only makes financial sense if I am biamping, and biamping gets most gains when an active crossover is used.
But this is not to say that biwiring with a single amp, or biamping without an active crossover don't make a difference ... just they aren't the optimal use of resources.
