Pass Labs Aleph Amps With Dynaudio Speakers?

Have Dynaudio Contour 3.3 speakers mated with a pair of Pass Labs Aleph 1.2 amps. I'm not quite sure if that is the best combo. The midrange is wonderful, but I feel it is lacking dynamics and the bass could be a little better. I think the speakers may require more current than the amps are capable of. I'm wondering if I would be better off with one of the Pass X series amps (250 or 350), or maybe the Ayre V1x (I 'm using the Ayre K1x Preamp). Any input would be greatly appreciated. Thanks.
