Looking at specs and measurements of the Mozarts on Stereophile they will benefit in teh bass largely from lots of power and sufficient current to drive them.
The Bel Canto Ref1000m Class D amps I use with my more full range speakers would be perfect but those are somewhat pricey.
A <$1000 250w/ch or more Class D Audio brand amp would be a reasonable try to see what might be weaned out of the Mozarts for not very much.
If you have an amp capable of driving those to the max, especially the fairly extended bass being delivered out of smaller drivers, all the rest may well clear up as well and sound more competitive with what appear to be the much smaller Wavetouch speakers.
The Wavetouch speakers are smaller and do not appear to have as extended a low end so finding a suitable amp to make those sound good is likely not as hard.
